What is the difference between linear and nonlinear equations?

Back

Linear equations graph as straight lines and have a constant rate of change, while nonlinear equations graph as curves and have varying rates of change.

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.
