question 5 hel ppleade ill give brainliest hdhshdhdh

Answer:
C (Kinda blurry)
Step-by-step explanation:
By looking at the two points you can tell the slope is 1, because it moves 2 over it moves 2 up.
If you back track to find the y value when x=0, then you have the x intercept.
So the equation is y=x+2. In this equation the values are jumbled so you just do a few transformations to make the equation look like the correct one.
subtract y on each side to get 0=x-y+2
subtract 2 from each side to get -2=x-y
now you have x-y=-2
