#y=-9 rarr x=-17#
#y=-8 rarr x=-16#
#y=-6 rarr x=-14#
#y=-5 rarr x=-13#
#y=-4 rarr x=-12#
#y=-3 rarr x=-11#

Explanation:

If #y# varies directly as #x#, then when #x# is increased or decreased by a number #n#, so will be #y#.

If #y=2# when #x=-6# then:

#y=-9=2-11 rarr x=-6-11=-17#
#y=-8=2-10 rarr x=-6-10=-16#
#y=-6=2-8 rarr x=-6-8=-14#
#y=-5=2-7 rarr x=-6-7=-13#
#y=-4=2-6 rarr x=-6-6=-12#
#y=-3=2-5 rarr x=-6-5=-11#
