Question

What is the slope of the line passing through the points (9, -7) and (3, -9)

Answer 1

m = 3

Explanation:

Notice how x increases by 6 from 3 to 9. 6 is the 'rise.'

Simultaneously, y increases by 2 from -9 to -7. 2 is the 'run.'

The slope, m, is defined as m = rise / run.

Here, m = 6/2, or m = 3
