Q. What is the equation of the vertical line through (−8,5) ?
Recalling the equation of a vertical line: Recall the general form of the equation of a vertical line. A vertical line has an undefined slope and is parallel to the y-axis. The equation of a vertical line is given by x=a constant value, where the constant is the x-coordinate of any point the line passes through.
Identifying the x-coordinate: Identify the x-coordinate of the given point (−8,5) through which the vertical line passes. The x-coordinate is −8.
Writing the equation of the vertical line: Write the equation of the vertical line using the x-coordinate from the previous step. Since the line is vertical, its equation will be x=−8.
