(0,0) and (2,1)
slope = -2
(1.-3) and (-1,-3)
slope = 1/2
(-1,3) and (-1,-3)
no slope
(0.7) and (2,4)
slope = -3/2
(0,-1) and (2,-5)
zero slope

Abilliard ball is struck by a cue. it travels 1 0 0 cm 100cm before ricocheting off a rail and traveling another 1 2 0 cm 120cm into a corner pocket. the angle between the path as the ball approaches the rail and the path after it strikes the rail is 4 5 ∘ 45 ∘ . how far is the corner pocket from where the cue initially struck the ball? do not round during your calculations. round your final answer to the nearest centimeter.
