the answer is graph a. the equation for slope intercept form (where the equation meets the y-axis) is y=mx+b.
y- the point the equation meets the y-axis
m-slope
x-whatever x equals in the equation
b-i think b is the point where the equation meets the x-axis, but i'm not sure about that... its been awhile since i learned
using the equation y=-1.5x, all you have to do is multiply x by -1.5, so if x=1 then y would equal -1.5 so there would be a point at (1, -1.5). if x=2, then y=-3 and there would be a point at (2, -3) and so on...
