Question

Find the slope of the line that passes through each pair of points.
(5, 7), (1, -3)

Answer 1

5/2 or 2.5

Explanation:

Slope is rise/run. We take the difference of the y-coordinates and divide it by the difference of the x-coordinates.

From this, we get
`(7--3)/(5-1)`, or
`10/4`, which can be simplified to 5/2, or 2.5.
