What is the slope of the line that passes through the points (5,6) and (5,9)?

undefined

Step-by-step explanation:

The slope of a line given two points is given by

m = (y2-y1)/(x2-x1)

   = (9-6)/(5-5)

   = 3/0

This slope is undefined

no slope

Step-by-step explanation: To solve this problem, we would usually use our slope formula but there is a faster way to solve this problem.

Notice that each ordered pair has the same x-coordinate which is 5.

Whenever you have the same x-coordinates, the line will have no slope.

That's because you must subtract the second y minus the first y over the second x minus the first x and you will end up with a denominator of 0 and you can't divide by 0.

Since any number divided by 0 is undefined, this line would be too.

If a line has no slope, it means that we cannot describe its slope using a number because the line is vertical and its slope is undefined.
