Equation of Line Parallel to the x-axis

A line that is parallel to the x-axis and has a y-intercept of c. has the equation y = c. The line is a horizontal line with a slope of 0.

This video provides an example of how to graph a horizontal line by using a table of values (T-table).




Equation of Line Parallel to the y-axis

A line that is parallel to the y-axis and has a x-intercept of a has the equation of x = a. The line is a vertical line that has no slope and no y-intercept. The slope is also said to be undefined.

This video provides an example of how to graph a vertical line by using a table of values.
The following video shows how to graph horizontal and vertical lines.
