Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the rise over run.

Front

Back

A positive correlation coefficient indicates that as one variable increases, the other variable also increases.

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

Back

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

Front

What does it mean if a line has a slope of 0?

Back
