Answer:
225
Step-by-step explanation:
Answer:
-The equation for the problem:
![y = \frac{1}{2}x + \frac{5}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7Dx%20%2B%20%5Cfrac%7B5%7D%7B2%7D)
Step-by-step explanation:
-First, you need determine the slope of a line:
(where
is the first coordinate and
is the second coordinate).
-Use both points
and
for the formula:
![m = \frac{5-2}{5+1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B5-2%7D%7B5%2B1%7D)
![m = \frac{3}{6}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B3%7D%7B6%7D)
![m = \frac{1}{2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
-After you have found the slope, use the point-slope formula and use the slope
and the first coordinate, which is
, to solve the equation and put it in slope-intercept form:
![y-y_{1} = m (x-x_{1})](https://tex.z-dn.net/?f=y-y_%7B1%7D%20%3D%20m%20%28x-x_%7B1%7D%29)
![y-2 = \frac{1}{2} (x+1)](https://tex.z-dn.net/?f=y-2%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%20%28x%2B1%29)
-Solve:
![y-2 = \frac{1}{2} (x+1)](https://tex.z-dn.net/?f=y-2%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%20%28x%2B1%29)
![y-2 = \frac{1}{2}x + \frac{1}{2}](https://tex.z-dn.net/?f=y-2%20%3D%20%5Cfrac%7B1%7D%7B2%7Dx%20%2B%20%5Cfrac%7B1%7D%7B2%7D)
![y = \frac{1}{2}x + \frac{5}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7Dx%20%2B%20%5Cfrac%7B5%7D%7B2%7D)
So, therefore the equation is
.
Answer:
y=mx+c
Step-by-step explanation:
where
m=slope
c=y intercept

Y= 2(x-3)^2
The 2 in front causes the vertical stretch and the -3 in the parenthesis is a right shift
