What is a horizontal line?

Back

A horizontal line is a straight line that runs from left to right across the page. It has a constant y-value and can be represented by the equation y = k, where k is a constant.

Front

What is a vertical line?

Back

A vertical line is a straight line that runs up and down the page. It has a constant x-value and can be represented by the equation x = k, where k is a constant.
