Answer:
Step-by-step explanation:
In order to find the slope of a line, we need to find the rise over the run.
Basically - the change in y divided by the change in x.
We can compare the two points and find both.
We go from (0, 2) to (3, 1).
From 0 to 3 (x) is 3 units.
From 2 to 1 (y) is -1 units.
Therefore we can divide the x by the y.
