what is the slope of the following 2 points (0,-3) and (0,5)
-3-5/0-0. The numerator is not what is important. The denominator forces division by zero which is undefined. Some people say that this is no slope, but undefined makes more sense to me. It has a slope, but you just can not define it because it is a vertical line stretching straight up and down. If the top number would have been zero, you would have had a horizontal line straight across with 0 slope.
GIVEN: (0 , -3) . (0 , 5).
Slope = (5 + 3) / 0 = Undefined.
