Question

What is the slope of the line that contains the points (-2, 8) and (-2, 1)?

Answer 1

The slope is undefined.

Explanation:

We have the coordinates `(-2, 8)` and `(-2, 1)`

The formula to find the slope of a line is `("change of y")/("change of x")` or `(y_2-y_1)/(x_2-x_1)`, where `x` and `y` are the points of two coordinates.

In this example we are given two coordinates so we can plug them into the formula:
`(1-8)/(-2-(-2))`

And now we simplify:
`-7/(-2+2)`

`-7/0`

undefined

The slope is undefined.

Hope this helps!
