Horizontal and Vertical Lines

Front

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 slope of 0 and can be represented by the equation y = b, where b is the y-intercept.

Front

What is a vertical line?

Back

A vertical line is a straight line that runs up and down the page. It has an undefined slope and can be represented by the equation x = a, where a is the x-intercept.
