Linear equations like y = 2x + 7 are called "linear" because they make a straight line when we graph them. These tutorials introduce you to linear relationships, their graphs, and functions.

Think of linear as just a line. A linear function is one that, when graphed, forms a line. Linear functions are in the form: f(x) = ax + b, where a and b are constants.

Zachary, One way to say it is that: A linear function is an equation that's solution set of (x,y) pairs when graphed would create a line on the graph.
