Question

A rectangular billiard table has vertices at p(0,0) ,q(0,7),r(10,7) s(10,0).A small billard ball starts at m(3,4) and moves in a straiht line to the top of the table,and bounces to the right side of the table ,then comes to rest at n(7,1).The y-coordinate of points where it hits the right side is

Dear student,

Since the ball starts at (3,4) and comes to rest at (7,1) afetr bouncing, so the y coordinates should be y=5
