Question

How do you write an equation in point slope form that passes through (5,-8) , (-9,-8)?

Answer 1

Since `y` is unchanged between these two points, while `x` changes, the slope `m = 0`. The line is parallel to the `x` axis.

It can be written in point-slope form as:

`y - (-8) = 0(x - 5)`

...using the point `(5, -8)`

More simply, its equation is simply `y=-8`, but that's not point-slope form.
