Slope describes the steepness of a line. It is the ratio of the rise, or vertical change, to the run, or horizontal change, of
a line.
Slope is a rate of change. Linear functions/equations have a constant rate of change.
There are multiple types of slope.
1. Positive (increasing from left to right)
2. Negative (decreasing from left to right)
3. Zero (horizontal line)
4. Undefined (vertical line)
HOW TO FIND THE SLOPE OF A LINE. Use a slope triangle to determine the rise and run.
Find the slope of the line that passes through the points (3 , 2) , (10 , 8).
