Question

Using the slope formula, find the slope of the line through the given points.
(7,9) and (9,5)

Answer 1

-2

Explanation:

The slope formula is change in y over change in x, so we take the y coordinates of the pair of points, and divide it by the x coordinates of the pair of points to get:

`(9-5)/(7-9)`

Simplifying this we get:

`-2`
