What is the y-intercept of a line?

Back

The point where the line crosses the y-axis.

Front

How do you graph a linear equation?

Back

By plotting points that satisfy the equation and connecting them.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.
