Use one of two methods to find the slope, given a graph.
-3/8
Practice makes perfect
Observing the given graph, we can see that the line passes through the points (-5,2) and (3,-1). One way to use a graph to find the slope of a line is to count the change in x and y.
We can tell from the given graph that the rise, or change in y from left to right, is -3. We can also see that the run, or change in x from left to right, is 8.
slope=rise/run ⇔ m=-3/8
We can confirm this answer by using the other method, the Slope Formula.
m = y_2-y_1/x_2-x_1
Let's use the given points to solve for the slope.
