What is the slope of a linear function?

Back

The slope of a linear function represents the rate of change of the function. It is calculated as the change in the y-values divided by the change in the x-values.

How do you determine the slope from a graph?

Back

To determine the slope from a graph, select two points on the line, calculate the rise (change in y) and run (change in x), and then divide rise by run.
