A vertical line has the same x-coordinate for every point on the line. This means that no matter what the y-coordinate is, the x-coordinate will remain constant. For a vertical line passing through the point (5, 2), the x-coordinate is 5.
Therefore, the equation of the vertical line can be expressed as:
x = 5
This means that any point on this vertical line will have an x-coordinate of 5, while the y-coordinate can be any real number. So, examples of points on this line include (5, 0), (5, -3), (5, 7), and so forth.
In summary, if you are looking for the equation of a vertical line that passes through the point (5, 2), it is simply x = 5.
