Answer:
17. A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right.
18. Zero slope means that the line is horizontal. Just like the line that makes the top of a “Z” is horizontal. No slope means that the line is vertical.
19. Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.
20. Yes, they did because 2/6 is equivalent to 1/3.
21. A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.

Hi there!

I believe your answer is:
[tex]y = 7x - 3\leftarrow \text{No.}\\\\y = 150x \leftarrow \text{Yes.}[/tex]
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
[tex]\boxed{\text{General Proportional Formula:}}\\\\y = kx\\\rule{150}{0.5}\\$\bullet \text{ } k - \text{Constant of Proportionality}\\\rule{150}{0.5}\\\text{Since } y=150x \text{ is in this form, we can say that it is a proportional relationship.}\\\rule{150}{0.5}\\\text{We can also tell if something is proportional by graphing them.}[/tex]
[tex]\textbf{Proportional graphs go through the origin.}[/tex]
⸻⸻⸻⸻
Since y = 7x - 3 does not pass the origin, it is not proportional. However, y = 150x does, so it is proportional.

If 2k - 3 = 9 (k+7)-3 then k is ????
Answers
Answer:
k= -9
Step-by-step explanation:
2k-3=9k+63-3 [expand the 9(k+7) first]
2k-9k=63-3+3 [put the like terms together]
-7k=63 [do the simple math]
k= 63 ÷ by -7
k=-9
Answer:
K = -9
Step-by-step explanation:
2k-3 = 9(k+7)-3
2k-3 = 9k+63-3
2k-3 = 9k+60
2k-9k = 60+3
-7k = 63
-k = 9
k = -9

y = -3x/5 + 4 halp
Answers
Answer:
3x+5y=20
Step-by-step explanation:
Answer:
3x + 5y = 20
Step-by-step explanation:
The given y = -3x/5 + 4 is in slope-intercept form. We are to put it into standard form, which would be Ax + By = C.
Start by eliminating the fraction representing the slope (-3/5); to do this, multiply all three terms by 5:
5y = -3x + 20
Next, rearrange the terms to resemble Ax + By = C:
3x + 5y = 20

What the equation in point-slope form, matchs the graphed line shown
Answers
Let (x1, y1) = (0, 1)
(x2, y2) = (-7, 5)
First, solve for the slope of the line using the formula:
m = (y2 - y1)/(x2 - x1)
m = (5 - 1) / (-7 - 0)
m = 4/-7 = -4/7
Now that we have our slope, m = -4/7, we can plug this in, along with one of the given points, (0, 1), into the point-slope form:
y - y1 = m(x - x1)
y - 1 = -4/7(x - 0) ← This is the point-slope form

Answer:
hat = 5pumpkin = 2ghost = 7cauldron = 10Step-by-step explanation:
Using h, p, g, c to represent the values of the hat, pumpkin, ghost, and cauldron, respectively, we can write 5 equations:
gh +h = 40cp +p = 22g +2c = 27ph +g = 172g +h = 19Solving the last equation for h, and substituting into the first equation gives ...
h = 19 -2g
g(19 -2g) +(19 -2g) = 40
2g^2 -17g +21 = 0 . . . . . . . . write in standard form
(2g -3)(g -7) = 0 . . . . . . . factored form
The values of g that make the factors zero are g = 3/2 and g = 7. If we assume the solution is restricted to integer values, then g = 7, and ...
h = 19 -2·7 = 5
From equation 4, ...
5p +7 = 17 ⇒ p = 2
From equation 3, ...
7 +2c = 27 ⇒ c = 10
The values of the symbols are ...
hat = 5pumpkin = 2ghost = 7cauldron = 10_____
