Answer:

Explanation:

Equation of a line giving 2 points is

y-y1=m(x-x1) where m is the slope and (x1,y1) is one of the points.

First we have to find the slope using formula

(y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are the points given

Slope m is (4-13)/(8--4) =-9/12 = -3/4

Looking at the answer choices, the only slope intercept equation that use the slope -3/4 is answer choice A
