The equation of the line passing through (-4,-6), (5,-6) will be y = -6
In the given question, it is stated that the line passes through points (-4,-6), and (5,-6). We need to find out an equation of the line that satisfies the given condition.
Firstly, we will need to find out the slope of the line. We can find the slope by using the point-slope form which is represented by:
=> [tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} }[/tex]
Putting values (x₁, y₁) = (-4,-6) and (x₂, y₂) = (5,-6) we get:
=> [tex]m = \frac{-6+ 6 }{5+ 4 }[/tex]
=> m = 0
We get slope m = 0. Now, putting the value of slope into the point-slope form and taking (x₁, y₁) = (-4,-6), we get values:
=> y - y₁ = m(x - x₁)
=> y + 6 = 0(x + 4)
=> y = -6
Hence, we get the equation of line y = -6

x = 8.27 rounded to the nearest tenth
Answer:
x = 8.3
Step-by-step explanation:
We look at the final place of the decimal to round, in this case the thousandths place (underlined)
8.27
If the final place of the decimal is greater than or equal to 5, we round up the decimal to the left, otherwise we round down.
Because 7 > 5, round 2 up to 3, therefore giving 8.3
Answer:
Your answer is 8.3!
Step-by-step explanation:
Step 1: Locate and underline the tenths place (2) then look at the digit to the right (7):
8.27
Step 2: In this case, the digit to the right (7) is 5 or above. So, we add 1 to the tenth place (2). The digit(s) after the (2) are replaced by zeros (or dropped). Thus, we get 8.3 as the answer.
In short: 8.27 rounded to the nearest tenth is 8.3.

Find the slope of the following equation. Simplify your answer.
5x + 2y = -10 And do not tell me it’s m= - 5/2 because clearly that’s not an option
The correct answer is: [D]: " [tex]m = \frac{-5}{2}[/tex] ".
______
Step-by-step explanation:
We are given:
" 5x + 2y = -10 " ; Find the slope of the equation.
______
Rewrite this equation in slope-intercept format ;
that is: " y = mx + b " ;
in which:
y remains as single value, as an 'output' ; or 'dependent
variable', on the 'y-axis' (if graphed);
isolated on the 'left-hand side' of the equation.
m is the coefficient of x in the equation; and represents the slope; for which we shall solve.
{If there is no slope, then "m = 0" ; and "[0 * x = 0]." };
And the "slope-intercept format" is: "y = b" }.
b represents the "y-intercept" ; i.e. when the line crosses the
"y-axis" when graphed; that is, the "y-value" of the "coordinate" of the "y-intercept" ; [i.e. the value of "y" when "x = 0" ; so; " (0, b) ".
{ Note: b can equal "0" ; in those cases: y = mx + 0 ; write as " y = mx "}.
{ If there is no slope, [i.e. "m = 0" ; and no "y-intercept" ; [i.e. "b = 0"];
Then: write the equation accordingly—e.g. " y = [whatever number the graph represents]." }.
Also, note that b can be a "negative number"; as well.
In that case, write an equation in "slope-intercept format" ; that is;
→" y = mx + b " ; as: " y = mx " .
______
Given: " 5x + 2y = -10 " ;
Let's rewrite: ↔ " 2y + 5x = -10 " ; to get the "y-value" a bit closer to the 'left-hand side' of the equation.
Then: Let's subtract 5x from Each Side of the equation;
2y + 5x − 5x = -10 − 5x ;
to get: " 2y = -10 − 5x " ;
______
Method 1):
We have: " 2y = -10 − 5x " ;
Divide Each Side by 2 ; to isolate y on the 'left-hand side' of the equation, and to rewrite as an equation in the slope-intercept format :
2y / 2 = (-10 − 5x)/2 ;
→ [tex]y =\frac{-10-5x}{2}= \frac{-10}{2}-\frac{5x}{2}[/tex] ;
→ [tex]\frac{-10}{2} =[/tex] -10 ÷ 2 = -5 ;
Rewrite the equation by replacing " [tex]\frac{-10}{2}[/tex] " ; with: -5 ;
→ [tex]y = -5 - \frac{5x}{2}[/tex] ;
Then, rewrite to get the equation in "slope-intercept format"
→ [tex]y = -5 - \frac{5x}{2}[/tex] ;
[tex]= -5 + (-\frac{5x}{2})[/tex] ; ↔ Rewrite:
[tex]= \frac{-5x}{2} + (-5)[/tex] ; ↔ Rewrite again:
[tex]=\frac{-5x}{2} -5[/tex] ;
→ [tex]y = \frac{-5x}{2} -5[/tex] .
Note: " [tex]\frac{-5x}{2} = \frac{-5}{2} x[/tex] " ;
→ [tex]y = \frac{-5}{2}x-5[/tex] ;
This is the equation written in "slope-intercept format" ;
that is: " y = mx + b " ;
in which:
y is isolated as a single variable on the 'left-hand side' of the equation;
m = [tex]\frac{-5}{2}[/tex] ; which is the slope; which is also the "coefficient" of x ;
b = -5 ; which is the 'y-coordinate' of the "y-intercept" of the graph;
So, the slope; "m = -5/2" ; is the correct answer; which corresponds to:
Answer choice: [D]: " m = [tex]\frac{-5}{2}[/tex] " .
______
Method 2):
Given: " 5x + 2y = -10" ; Find the slope of the line.
We want to rewrite the equation in the "slope-intercept format" ;
" y = mx + b " ; as explained above;
to get the correct answer for m, the slope of the line.
" 5x + 2y = -10 " ↔ Rewrite as:
2y + 5x = -10 ; since we want to isolate y as a single variable on the 'left-hand side' of the equation; and by rearranging & rewriting this equation, the 2y is closer to the 'left' of the equation.
Now, subtract 5x from Each Side of the equation:
2y + 5x − 5x = -10 − 5x ;
to get: 2y = -10 − 5x ;
Now, Let's multiply the entire equation (i.e. "Each Side") by -1 ;
to make the equation easier to handle;
-1(2y) = -1 (-10 − 5x) ;
For the 'left-hand side' of the equation:
-1*2y = -2y
For the 'right-hand side' of the equation:
Note the 'distributive property of multiplication'; as follows:
a(b + c) = ab + ac ;
Likewise:
-1(-10 − 5x) = (-1 *-10) + (-1 *-5x) ;
= (10) + (5x) = 10 + 5x ;
Now, rewrite the entire equation:
-2y = 10 + 5x ; ↔ Rewrite as;
-2y = 5x + 10 ;
Then, we divide Each Side of the equation by -2 ;
to isolate y as a "single variable" on the 'left-hand side' of the equation;
and to rewrite the equation in "slope-intercept format" ;
-2y / -2 = (5x + 10) /-2 ;
→ [tex]y=\frac{5x+10}{-2} =\frac{5x}{-2} +\frac{10}{-2} =\frac{5x}{-2}+(-5) =\frac{5x}{-2}-5[/tex] ;
→ [tex]y=\frac{5x}{-2} - 5[/tex] ;
which is written in "slope-intercept format" ; that is:
" y = mx + b " ;
in which:
y is isolated as a single variable on the 'left-hand side' of the equation;
m = [tex]\frac{5}{-2}[/tex] ; which does equal " [tex]-\frac{5}{2}[/tex] " ; which does equal " [tex]\frac{-5}{2}[/tex] " ;
which is the slope of the equation, as well as the 'coefficent of x' ;
b = -5 ; which is the 'y-coordinate' of the "y-intercept".
______
As such:
The correct answer choice is: [D]: " m = [tex]\frac{-5}{2}[/tex] " .
{Note: This is consistent with the answer choice from Method 1 above.}

Hope this answer and explanation is helpful.

Characterize the slope of the line in the graph
A. Positive

C. Zero
D. Undefined
The slope of the line in the graph is undefined.
The line in the graph is a straight vertical line whose slope can be found.
The characteristics of a vertical line can be used to find the slope of the vertical line given.
A vertical line has same x-co-ordinate but will have different y-co-ordinates.
Slope of a line is the change in y-co-ordinates divided by change in x-co-ordinates.
That is, slope = change in y-co-ordinates/ change in y-co-ordinates
But here, change in x-co-ordinates is zero since the x-co-ordinates are same for the vertical line given in the graph.
So slope = change in y-co-ordinates/ 0
This is undefined.
So the slope of the line in the graph is undefined.

The lines are parallel.
The lines overlap at all points.
The lines intersect at (1.6,1.4).
The lines intersect at (3.1,0.5).
Answer:
3rd answer option (1.6, 1.4)
Step-by-step explanation:
the slope of the lines is different.
to see we transform the equations to the regular slope-intercept form
y = ax + b
with "a" being the slope and "b" being the y-intercept (the y value when x = 0).
1.5x + 0.2y = 2.68
0.2y = -1.5x + 2.68
y = -1.5x/0.2 + 2.68/0.2 = -7.5x + 13.4
1.6x + 0.3y = 2.98
0.3y = -1.6x + 2.98
y = -1.6x/0.3 + 2.98/0.3 = -5.33333...x + 9.93333...
-7.5 is not -5.3333...
so, the lines are not parallel nor overlap at all points.

1.5×1.6 + 0.2×1.4 = 2.68
1.6×1.6 + 0.3×1.4 = 2.98
2.4 + 0.28 = 2.68
2.68 = 2.68 correct
2.56 + 0.42 = 2.98
2.98 = 2.98 correct
yes, they intersect at (1.6, 1.4).
for (3.1, 0.5) already the x coordinate is way too large.
1.5×3.1 or 1.6×3.1 are already by themselves much larger than 2.68 or 2.98.
