The formula for slope intercept form is y=mx+b where x is the slope and b is the y intercept. To find the slope you would have to do -2-7 over 8-0 and that would give you -9/8. That would be your slope. And I think you should be given a graph I’m not sure but if there is look at it and see what point you see on the y axis
8 is A
9 is D
10 is C
