There is no graph that you have attached. However, I can still help:
Look at all the options. The one that starts off at negative 4 and moves up by 2 units per one horizontal unit positively should be the correct one.
How I figured it out:
y = mx + b
y - b = mx
-b = mx - y
4 = 2x - y
m = slope
b = starting point/intercept
Hope this helps!! :)
