Line AB contains points A (−3, 5) and B (−3, 3). Line AB has a slope that is
slope = y1-y2/x1-x2 .. 5-3/-3--3 = math error (its parallel to y axis)
You have to take the both y coordinates and subtract and then take both x coordinates and subtract them too then you'll end up with a y/x answer so u have to divide it and that'll be ur answer if its not divisible then u will stay with that fraction
