Length: 
60% of 6 is 3.6
3.6 x 6 = 21.6 
Width: 
150% of 5 is 7.5 
7.5 x 5 = 37.5 
So her mothers garden should be 21.6 feet in length, and 37.5 feet in width.

Direct variation is of the form y=kx.  We are given the point (8, -4) so we can solve for k, the constant of variation...
-4=8k, divide both sides by 8
-4/8=k
k=-0.5, so our equation is:
y=-0.5x,
