Vertical Line
A vertical line is a straight line that goes up and down, parallel to the y-axis on a coordinate plane. It has the equation x = k, where k is the x-coordinate of the points on the line.
Characteristics of a Vertical Line
- Direction: A vertical line goes straight up and down.
- Equation: The equation of a vertical line is always in the form x = k, where k is the x-coordinate of any point on the line.
- Slope: The slope of a vertical line is undefined because the rise (change in y) is 0, and division by 0 is undefined.
- Parallel: All vertical lines are parallel to each other.
Graphing a Vertical Line
To graph a vertical line with equation x = k, locate the value of k on the x-axis and draw a straight line passing through that point. The line will be parallel to the y-axis.
