Answer:
a
Step-by-step explanation:
I'm pretty sure it would be <span>x - y + 1 = 0 because if you plug in one of the coordinates into each equation, this is the only one that works.
</span><span>y - x + 1 = 0
2 - 1 + 1 = 0
2 = 0 not correct
</span><span>x - y + 1 = 0
1 - 2 + 1 = 0
0 = 0 correct
</span><span>-x - y + 1 = 0
-1 - 2 + 1 = 0
-2 = 0 not correct
</span>
Step-by-step explanation:
Move it it up 4 and then find your x intercepts.
Find the x intercepts.

<u>Move the 4 over to the right</u>

<u>Divide out the - </u>


<u>Take the square root of each side</u>


Our x intercepts are at (-2,0) (2,0)
