Answer:
y=2/2 x -800
Step-by-step explanation:
if you look the line intercepts Y at -800 and slope form is y=mx+b and B is your Y-intercept so you can easily find that. Now the next time the line touches a point on the graph is 2 points up and 2 points to the right, so your slope is 2/2. Remember your slope is always rise over run.
