A line passes through the points (-3,-5) and (-6,1). The equation of this line can be expressed in the form Ax + By = C, where A, B, and C are integers with greatest common divisor 1, and A is positive. Find A + B+ C.

Slope,m, between the points = -6/3 = -2

 

point slope form    (using point (-3,-5) <====== you could use the other point instead....same result)

 

(y+5)= -2(x+3)    re-arrange

2x + y = -11          you can finish, I hope !
