Example 1: Write an equation for the following line: Graph of a Line Since y always takes the value -1, an equation for the line … Remember that vertical lines only have a 'y' value and no 'x' value. I also love learning new things and taking on new challenges. Required fields are marked *. The line passes through the x x -axis at (a,0) (a, 0). (-2,-3) Horizontal lines are said to be horizontal to the horizon. No, a horizontal line has no slope, i.e., the slope of a horizontal line is 0. Remember that vertical lines only have a 'y' value and no 'x' value. Improve your math knowledge with free questions in "Equations of horizontal and vertical lines" and thousands of other math skills. The equation x = 4 represents a vertical line which crosses the x -axis at the point ( 4 , 0 ) .
