If y varies directly as x ad y=7 when x=-5, find y when x is 20

Y would equal -28 when X equals 20.

Since they vary directly, all you do is divide 20 by -5 to find the variation between X and Y. You will get -4 which you multiply to 7, to get you final answer. Thus making Y equal to -28.

I hope this helps!
