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 !
