Count out the change in x and y to find the slope.
- 2
Practice makes perfect
Observing the given graph, we can see that the line passes through the points (0,1) and (3,- 5). To find the slope of a line we will count out the change in x and y.
We can see that as the graph travels from left to right, the rise, or change in y, is - 6. Similarly, the run, or change in x, is 3.
slope=rise/run ⇔ m=- 6/3=- 2
The slope of the given line is - 2.
