The first thing you should do in this case is to write the equation in its generic form. We have then: y-yo = m (x-xo) We look for the slope: m = (y2-y1) / (x2-x1) m = (0-3) / (3 - (- 2)) m = -3 / 5 We choose any point of the line: (xo, yo) = (- 2, 3) We substitute the values in the generic equation: y-3 = -3 / 5 (x - (- 2)) We rewrite: y-3 = -3 / 5 (x + 2) Answer: b) (y - 3) = - 3/5 (x + 2)
