Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, meaning it does not rise or fall as it moves along the x-axis.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined because it does not have a change in x (it runs parallel to the y-axis).

Front

How do you identify a horizontal line on a graph?

Back

A horizontal line can be identified on a graph as a line that runs parallel to the x-axis and does not change in height.

Front

How do you identify a vertical line on a graph?

Back

A vertical line can be identified on a graph as a line that runs parallel to the y-axis and does not change in width.

Front

If a line has a slope of 0, what type of line is it?

Back

A line with a slope of 0 is a horizontal line.
