Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-coordinate with respect to the x-coordinate. It indicates how steep the line is.

Front

What is a positive slope?

Back

A positive slope means that as the x-value increases, the y-value also increases. The line rises from left to right.

Front

What is a negative slope?

Back

A negative slope means that as the x-value increases, the y-value decreases. The line falls from left to right.

Front

What is a zero slope?

Back

A zero slope indicates a horizontal line where the y-value remains constant regardless of the x-value.

Front

What is an undefined slope?

Back

An undefined slope occurs in a vertical line where the x-value remains constant, and the y-value can change.

Front

What does it mean for a line to be increasing?

Back

A line is increasing when the slope is positive, meaning that as you move from left to right, the y-values increase.

Front

What does it mean for a line to be decreasing?

Back

A line is decreasing when the slope is negative, meaning that as you move from left to right, the y-values decrease.
