Question

What is the slope and of the line that passes (-2, -4) and (-7, -4)?

Answer 1

`0`

Explanation:

To get the slope, it might be easier for you to make a table:

`x:" " -2 , -7`

`y:" " -4 , -4`

A slope is the change in `y` over the change in `x`. To get the change, you subtract, `-4` minus `-4` is `0`. `-2` minus `-7` is `5`.

`(-4 - (-4))/(-2 - (-7)) = 0/5 = 0`

This line has no slope. It is a straight line parallel to the x-axis.
