This is the complete question.
Y varies inversely as the square of x when x=6 y=4, how do you find y when x=2
y=36
Explanation:
y varies inversely as the square of x means:
y=kx2
Solving for k:
k=x2y
k=(6)2(4)
k=
To find y when x=2, we go back to the orinal equation:
y=k(2)2
y=(6)244
y=36

If y varies inversely then y=k/z where k is constant

When x=2 and y=6, k=2*6 =12

Law of variation
y = 12/x

y¤1/x
y=k/x
k=xy
y=6,x=2
k=2*6
k=12
the law of variation is;
y=12/x
