Find slope slope betwen 2 points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so first make denoms same denom is 10 (4/5,1/5) turns to (8/10,2/10) (1/2,3/2) turns to (5/10,15/10) slope=(15/10-2/10)/(5/10-8/10)=(13/10)/(-3/10)=13/-3=-13/3
use point slope use (4/5,1/5) y-y1=m(x-x1) a point is (x1,y1) and slope is m y-1/5=-13/3(x-4/5) expand wait, we don't need to do that, the only one with slope -13/3 is D answer is D
