The slope of the line that contains the given point is the rise/run, which is: 1/8.
The slope of a line = rise / run = change in y / change in x.
Given the points on a line as (9, –4) and (1, –5):
Change in y = (-4 -(-5) = 1
Change in x = (9 - 1) = 8
Slope of the line = change in y/change in x = 1/8.
