Graphing is an excellent tool to teach the concept of linear and nonlinear functions visually. Provide students with a graph and a set of data, including both linear and nonlinear functions, and ask ...

A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation.

If two linear functions have the same slope they are parallel. Slopes of linear functions The slope of a linear function is the same no matter where on the line it is measured. (This is not true for ...

Ever wonder what sorts of errors freshman math students make? There are a couple of pretty basic ones.
