y = - 3
Since y varies directly as x then 
y = kx ← ( k is the constant of variation )
to find k use y = - 1 when x = 3
k =  =
 =  = -
 = - 
hence y = -  x
 x
when x = 9, then
y = -  × 9 = - 3
 × 9 = - 3

Answer:
4 players and 1 instructor
Step-by-step explanation:
If all 4 players pay $300 each, that equals $1,200. The instructor will get $1,000 of it. That means there is $200 left. They need 40 balls per player. Each ball is $1, so that's $40 per player. 40 x 4= 160    200-160 = 40 The club will have $40 left.
