Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

How do you convert the slope-intercept form to standard form?

Back

Rearrange the equation y = mx + b to Ax + By = C.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.
