What does the term 'rise over run' refer to?

Back

'Rise over run' refers to the calculation of slope, which is the vertical change (rise) divided by the horizontal change (run) between two points on a line.

How can you determine if a function is linear from its graph?

Back

A function is linear if its graph is a straight line. If the graph curves, the function is nonlinear.
