Question

Find the slope of the line that contains (4, -6) and (4, 4)

Answer 1

Undefined.

Explanation:

Use the slope formula:
`(y_1-y_2)/(x_1-x_2)`

`m=(-6-4)/(4-4)=(-10)/(0)=` Undefined

Answer 2

Undefined

Explanation:

Slope formula =
`(y_(2)-y_(1))/(y_(2)-y_(1))`

`(4-(-6))/(4-4)`

`(10)/(0)`

A number can not have a denominator of 0, therefore making the slope undefined.
