Rate of change: graphs
Find slope from a graph using rise over run.
Lesson 7
Concept
Choose two points on the line, measure vertical change (rise) and horizontal change (run), then compute rise/run.
Try it
On a graph, points (0, -2) and (3, 4) lie on a line. Find slope.
Slope from graph steps
These steps are out of order — can you fix them?
1.Compute rise
2.Simplify rise/run
3.Select two clear points
4.Compute run
