Solutions to the equation correspond to shared graph points, not to the number of curves drawn. We’ll trace the two complete lines and count each distinct place where they have the same horizontal and vertical coordinates. Their slope directions also tell us whether they can meet again after a crossing, which guards against counting a visible line or segment as an additional solution.
