How do you determine the rate of change from a graph?

Back

The rate of change is determined by calculating the slope of the line, which is the change in the y-values divided by the change in the x-values (rise/run).

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the ratio of the vertical change to the horizontal change between two points on the line.
