Which statements are true? Check all that apply.

A horizontal line has the same y-coordinate at every point. In A, both points have y = 7, so the line is horizontal. In B, x = −8 fixes the x-coordinate, making a vertical line that passes through (−8, 3); in C, both points have x = 0, so their line is vertical. D is false because points on a horizontal line share the same y-coordinate, not the same x-coordinate.
