Question

What is the slope of the line that passes through the points (-7, -7) and (-7, 1)? Write your answer in simplest form.

Answer 1

undefined, stays on x so straight vertical - vertical line is undef slope

Answer 2

Answer: The slope is undefined

Explanation:

The slope of a line is calculated using the formula :

m =
`(y_(2)-y_(1))/(x_(2)-x_(1))`

`x_(1)` = -7

`x_(2)` = -7

`y_(1)` = -7

`y_(2)` = 1

Substituting the values into the formula , we have :

m =
`(1-(-7))/(-7-(-7))`

m =
`(8)/(0)`

m = undefined
