Answer:
The slope of a line characterizes the direction of a line.
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
Example:
(3,2) and (4,1)
3 - 4 = -1
2 - 1 = 1
-1 divided by 1 is -1. That's the slope, -1.
