Full solution

Q. What is the equation of the vertical line through (8,5)(-8,5) ?
  1. 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 valuex = \text{a constant value}, where the constant is the xx-coordinate of any point the line passes through.
  2. Identifying the x-coordinate: Identify the x-coordinate of the given point (8,5)(-8,5) through which the vertical line passes. The x-coordinate is 8-8.
  3. Writing the equation of the vertical line: Write the equation of the vertical line using the xx-coordinate from the previous step. Since the line is vertical, its equation will be x=8x = -8.
