Answer:
A. y + 2= x
Step-by-step explanation:
Which equation is represented by the graph shown in the image?
A. y + 2= x
B. y + 1= x
C. y - 1= x
D. y - 2= x
Please show ALL work! <3
The graph shown has a slope of +1 and a y intercept of -2.
All given answer choices have a slope of +1, so that's not the problem.
We need one that has a y-intercept of -2, or the equation should be
y = x-2, or equivalently y+2 = x
which corresponds to answer choice A.

Answer:
![A.\ (\frac{3}{2}, \frac{9}{2})](https://tex.z-dn.net/?f=A.%5C%20%28%5Cfrac%7B3%7D%7B2%7D%2C%20%5Cfrac%7B9%7D%7B2%7D%29)
Step-by-step explanation:
Given
![y = x^2](https://tex.z-dn.net/?f=y%20%3D%20x%5E2)
Required
Determine which of the given points is not true
![A.\ (\frac{3}{2}, \frac{9}{2})](https://tex.z-dn.net/?f=A.%5C%20%28%5Cfrac%7B3%7D%7B2%7D%2C%20%5Cfrac%7B9%7D%7B2%7D%29)
Here
and ![y = \frac{9}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B9%7D%7B2%7D)
Substitute these values in ![y = x^2](https://tex.z-dn.net/?f=y%20%3D%20x%5E2)
![\frac{9}{2} = (\frac{3}{2})^2](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B2%7D%20%3D%20%28%5Cfrac%7B3%7D%7B2%7D%29%5E2)
![\frac{9}{2} = \frac{3}{2}*\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B2%7D%20%3D%20%5Cfrac%7B3%7D%7B2%7D%2A%5Cfrac%7B3%7D%7B2%7D)
![\frac{9}{2} \ne \frac{9}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B2%7D%20%5Cne%20%5Cfrac%7B9%7D%7B4%7D)
<em>Both sides of the equation are not equal. Hence, this point do not line on the curve</em>
<em></em>
![B.\ (-1, 1)](https://tex.z-dn.net/?f=B.%5C%20%28-1%2C%201%29)
Here
and ![y = 1](https://tex.z-dn.net/?f=y%20%3D%201)
Substitute these values in ![y = x^2](https://tex.z-dn.net/?f=y%20%3D%20x%5E2)
![1 = (-1)^2](https://tex.z-dn.net/?f=1%20%3D%20%28-1%29%5E2)
![1=1](https://tex.z-dn.net/?f=1%3D1)
<em>Both sides of the equation are equal. Hence, this point line on the curve</em>
![C.\ (4, 16)](https://tex.z-dn.net/?f=C.%5C%20%284%2C%2016%29)
Here
and ![y = 16](https://tex.z-dn.net/?f=y%20%3D%2016)
Substitute these values in ![y = x^2](https://tex.z-dn.net/?f=y%20%3D%20x%5E2)
![16 = 4^2](https://tex.z-dn.net/?f=16%20%3D%204%5E2)
![16 = 16](https://tex.z-dn.net/?f=16%20%3D%2016)
<em>Both sides of the equation are equal. Hence, this point line on the curve</em>
![D.\ (\frac{1}{2}, \frac{1}{4})](https://tex.z-dn.net/?f=D.%5C%20%28%5Cfrac%7B1%7D%7B2%7D%2C%20%5Cfrac%7B1%7D%7B4%7D%29)
Here
and ![y = \frac{1}{4}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
Substitute these values in ![y = x^2](https://tex.z-dn.net/?f=y%20%3D%20x%5E2)
![\frac{1}{4} = (\frac{1}{2})^2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%3D%20%28%5Cfrac%7B1%7D%7B2%7D%29%5E2)
![\frac{1}{4} = \frac{1}{2}*\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A%5Cfrac%7B1%7D%7B2%7D)

<em>Both sides of the equation are equal. Hence, this point line on the curve</em>
<em>From the calculations above; only </em>
