Front

What is the standard form of a linear equation?

Back

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

How do you find the slope from the equation 7x + 2y = -28?

Back

Rearranging gives y = -7/2x - 14, so the slope m = -7/2.

What does the y-intercept of a line represent?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.
