Question

What is the slope of the line through the points (-2,4) and (1,2)

Answer 1

The slope is
`(-2)/(3)`

Explanation:

An order pair is in the form (x y). The slope is the change in y over the change in x. From the 2 points our y's are 2 and 4. From the 2 points our x's are 1 and -2. to find the change you subtract.

`(2-4)/(1 - -2)` =
`(-2)/(1 + 2)`
`(-2)/(3)`
