When you have the line already graphed, count the "rise over run"
When you don't have a graph, but 2 points instead, use the "Slope Formula"But it really doesn't matter whether you do it graphically or algebraically because it is still the same slope either
way
There are two methods you can use to find the slope of a line: Algebraically or Graphically

Algebraically or Graphically ?????????
(3, 4) (-5, 0)
Find the slope of the line that passes through the points:
Algebraically(use the formula)

Use both methods: Algebraically
Finding the rate of change is the same as finding the slope:
