It is C because I can plot all those points and they are still on the blue line. If you don't believe me, plug them in to y=-3/2x+2, (-4,8 plugged in would look like this 8=-3/2(-4)+2 just plug the x and y coordinates in) and they will be correct.
Ok so let me help you with this. Here is the procedure: <span>r² = x² + y² = 8² + 6² = 100 r = 10 x = r cosθ y = r sinθ sinθ = y/r = 6/10 = 3/5 </span>Hope this is what you are looking for
