Answer:
x = 4
Explanation:
A vertical line passing through the point (4, -2) would have an undefined slope because it is parallel to the y-axis, and the equation of a vertical line passing through a point is of the form x = c, where c is a constant.
Since the line passes through the point (4, -2), the constant c in the equation x = c must be equal to 4, resulting in the equation:
x = 4
