calculate the slope of the line between the points (9, -8) and (9, 9)

Question

what is the slope? i came up with 17/0. is that 0? 

 

calculate the slope of the line between the points (9, -8) and (9, 9)

Answer 1

17/0 is undefined, as is any number that is divided by zero. For the level of mathematics you're in right now, this is the accepted answer.

Answer 2

What you did to get 17/0 is correct but that doesn't equal 0, 0/17 = 0. When you get a 0 in the denominator your slope is undefined.

Answer 3

17/0 means undefined term  and not equal to zero,which shows that the line passing through two points is

parallel to y-axis
