Answer:
y = -¼x + ½Step-by-step explanation:
Given points (-2, 1) and (6, -1):
Start by solving for the slope of the line, using the following formula:
m = (y2 - y1)/(x2 - x1)
Let (x1, y1) = (-2, 1)
(x2, y2) = (6, -1)
m = (y2 - y1)/(x2 - x1)
m = (-1 - 1)/[6 - (-2)]
m = -2/(6 + 2) = -2/8 = -¼
Therefore, the slope of the line is m = - ¼.
Next, to determine the y-intercept (b), use one of the given points (6, -1) and the slope, and plug in these values into the slope-intercept form:
y = mx + b
-1 = -¼(6) + b
-1 = -3/2 + b
-1 + 3/2 = -3/2 + 3/2 + b
½ = b
Therefore, the y-intercept, b = ½.
The linear equation of the given graph is:
y = -¼x + ½Related Questions

Answer: -6x
Step-by-step explanation: Since when x is 0, the function's output is 0, the function can only have terms with x in it. You then notice a pattern that x is always being multiplied by -6. You could also use point slope form to solve it, either way you get f(x)=-6x
Answer:
f(x) = -6x
Step-by-step explanation:
The linear equation given in the form of a table is shown as:
[tex]\left[\begin{array}{ccc}x&f(x)\\0&0\\1&-6\\2&-12\\3&-18\end{array}\right][/tex]
Because the equation is linear, in order to find the equation written in slope-intercept form, divide the rise (f(x)) by the run (x):
0 ÷ 0 = 8
-6 ÷ 1 = 8
-12 ÷ 2 = 8
-18 ÷ 3 = 8
Because the quotient for each relation is -6, the linear equation can be written as f(x) = -6x.

Step-by-step explanation:
It's easier to graph when both equations are in its slope-intercept form, y = mx + b.
System 1: -3x -15y = 15-2x -10y = 10-2x -10y = 10
-2x + 2x - 10y = 2x + 10
-10y = 2x + 10
-10y/-10 = (2x + 10)/-10
y = -1/5x -1 [slope: -1/5, y-intercept (0, -1)]
-3x -15y = 15
-3x + 3x - 15y = 15
-15y = 3x + 15
-15y/-15 = (3x + 15)/-15
y = -1/5x - 1 [slope: -1/5, y-intercept (0, -1)]
To graph this system, plot the y-intercept, (0, -1) on the graph, then use the slope, m = -1/5 (down 1 unit, run 5 units to the right). Repeat the process until you have enough points to connect and create a line.
Because the given systems of linear equations are equivalent, their lines coincide on top of each other. This means that they have infinitely many points of intersection. Hence, they have infinite solutions.
System 2: 8x + 6y = 244x + 3y = 98x + 6y = 24
6y = -8x + 24
6y/6 = (-8x + 24)/6
y = -4/3x + 4 [slope: -4/3, y-intercept (0, 4)]
4x + 3y = 9
3y = -4x + 9
3y/3 = (-4x + 9)/3
y = -4/3x + 3 [slope: -4/3, y-intercept (0, 3)]
Use the same techniques as described in the first part. Plot the y-intercepts on the graph, then use the slope of each equation to plot other points.
These lines are parallel, which implies that they will never intersect each other. Hence, there's no solution to this system.
Attached are the screenshots of the graphed systems of linear equations.

Step-by-step explanation: 12 months in one year. 12x50=600 months
Answer:
600 months
Step-by-step explanation:
In 1 year there are 12 months, so we take 50 (the years) and multiply that by 12
50x12=600 and we fact check by 600÷12=50. It takes 600 months to build the house over 50 years.

Find the slope intercept form of the equation of the line that’s has the given properties (1 , 3) m=1/4
Answers
Answer:
y = 1/4x + 11/4
Step-by-step explanation:
Given the slope, m = 1/4, and the point, (1, 3):
We can substitute these values into the slope-intercept form, y = mx + b, in order to solve for the y-intercept.
The y-coordinate (b) of the point, (0, b ) is the y-intercept of the line where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
y = mx + b
3 = 1/4(1) + b
3 = 1/4 + b
Subtract 1/4 from both sides:
3 - 1/4 = 1/4 - 1/4 + b
11/4 = b
The y-coordinate, b, of the y-intercept is 11/4.
Therefore, the slope-intercept form is: y = 1/4x + 11/4

Jacob went bowling over the weekend. On Saturday, he bowled at Bowlero, where he
rented shoes for $3.25 and paid $3.75 for each game. On Sunday, he bowled at the
Cowtown Bowling Center, where he rented shoes for $2.50 and paid $4.00 per game.
If he spent the same amount each day, how many games did he bowl? (Let the
number of games played = 2.)
Answers
Answer:
3 games played every Day
Step-by-step explanation:
So for Cowtown Bowling Center the cost of shoes is $2.50, and $4.00 per game
Then the Bowler is $3.25 for shoes and 3.75 per game
So to get the answer your gonna wanna set up the equation like
Saterday =$3.25+$3.75(x), then for
Sunday = $2.50+$4.00(x)
The X is how many games so if you plug in the same amount of game in both
Example
Saterday=$3.25+$3.75(2)=$10.75
Sunday = $2.50+$4.00(2)=$10.50
So if you do 3 then the totals will come out to be the same
Answer
Saterday=$3.25+$3.75(3)=$14.50
Sunday = $2.50+$4.00(3)=$14.50

C. x+8=3x
Step by step explanation:
First, subtract 8 from both sides of the equation
x+8=3x
x+8-8=3x-8
Then, simplify it by subtracting again
x+8-8=3x-8
x=3x-8
Then, subtract 3x from both sides of the equation
x=3x-8
x-3x=3x-8-3x
Then, simplify by combining the terms
x-3x=3x-8-3x
-2x=3x-8-3x
-2x=3x-8-3x
-2x= -8
Then, divide both sides of the equation by the same term
-2x= -8
-2x/-2 = -8/-2
Then, simplify by cancling terms that are in both the numerator and denominator
-2x/-2 = -8/-2
x= -8/-2
Finally, divide the numbers
x= -8/-2
x=4
