Question

Find the slope of the line that contains (6, 2) and (6,-3).

Find the slope of the line through the points (-4,-7) and (4, 3).

Answer 1

A. Undefined slope (no slope)

B.
`(5)/(4)`

Explanation:

A slope is rise over run.

The points (6, 2) and (6, -3) are located on the same x coordinate, therefore they have an undefined slope.

However, the points (-4, -7) and (4, 3) do have a slope. The rise is 10 ( | -7+ 3 | ) and the run is 8 ( | -4 + 4 | ). 10/8 is equivalent to 5/4.

Hope this helped!
