Can you guide me how to resolve this problem

Harry’s soccer team plays 2 nonconference games for every 3 games that they play against conference opponents. if y represents the number of nonconference games and x represents the number of conference games, which equation best models this proportional relationship? a)y=2/3 x b)y=3/2 x c)y = 2x d)y = 6x

If a is a nonzero real number then the reciprocal of a is

Which is the focus of a parabola with equation y2=4x
