Question 6
Find the slope of the line passing through the points (11,-5) and (11,6)

Answer 1

There are two ways to approach this.

Option #1:

Use the slope formula
`m = (y_2-y_1)/(x_2-x_1)`.

`m= (6-(-5))/(11-11) = (11)/(0)`

That value is undefined, so the slope is undefined.

Option #2:

Because the two points have the same x-value, they will be vertically above/below one another. This means your line is a vertical line and the slope of a vertical line is undefined.

Either way, your slope is undefined.
