Vertical and Horizontal Lines

Front

What is a vertical line?

Back

A vertical line is a straight line that goes up and down. It has an undefined slope and can be represented by an equation of the form x = a, where 'a' is a constant.

What is a horizontal line?

Back

A horizontal line is a straight line that goes left and right. It has a slope of 0 and can be represented by an equation of the form y = b, where 'b' is a constant.
