Question

What is the slope of the line through the points (5,2) and (5,-3)?

Answer 1

The formula we are using to find the slope is: `m=(y_"2" - y_"1")/(x_"2" - x_"1")`
=> where `m` is the slope, `y` is the y-component of the line (vertical), and `x` is the x-component (horizontal). The `1` and `2` are subscripts.

The subscripts don't really matter as long as you're consistent.

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

`= (-3-2)/(5-5)`

`= -5/0`

The slope of the line going through those points, is `-5/0`. Meaning the slope is going horizontal completely.

Hope this helps :)
