Front

How do you find the x-intercept of a linear equation?

Back

Set y=0 in the equation and solve for x.

Front

How do you find the y-intercept of a linear equation?

Back

Set x=0 in the equation and solve for y.

Front

What is the general form of a linear equation?

Back

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