A billiards table is 8 feet by 4 feet, and has pockets in all four corners and in the middle of the two longer sides; we can visualize this as a rectangle in R2 and assume that the bottom left pocket is at the origin and the top right pocket is at (8, 4). A ball starts at the point (1, 2) and is hit in the direction ⟨5, −2⟩. Does the ball go into a pocket before it bounces off three walls and, if so, which one?

The distance between the points (3, 8) and (r, 8x + 3) is
