Question

Calculate the slope between the points 3,7 and -3,7

Answer 1

The y-coordinate doesn't change at all, so there's no rise and slope = 0.

Answer 2

ya i got that but it wouldnt be undifined

Answer 3

Nope, you get something undefined only when you divide by 0. In orderd to get division by 0 while calculating slope, you would need to have the denominator = 0, so x2 - x1 would have to be 0. But that means x1=x2 and it makes no sense, because it's the same point.

Answer 4

ohh i get it.. thanks alot

Answer 5

No problem.
