The point P(-2, 7) lies on the vertical line x = -2. Option A is the only option that includes the correct x-coordinate of -2. Option B, y = 2 would result in a point (2, 7) which is not the given point. Option C, y = 7 would also result in a different point (2, 7) on the x-axis. Option D, x = -2, is the equation for the line itself rather than a point on the line. Therefore, the correct answer is A.
