Front

Define a linear equation.

Back

An equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x.

Front

What is the difference between independent and dependent variables?

Back

Independent variables are manipulated, while dependent variables are measured.
