6x-3y=18
y = 2x-6
-------------
Domain is:{-2,-1,1,3,4}
Range::
f(-2) = -4-6 = -10
f(-1) = -2-6 = -8
f(1) = 2-6 = -4
f(3) = 2*3-6 = 0
f(4) = 2*4-6 = 2

24. 6x-3y=18
Domain is:
{ -2,-1,1,3,4 }
if x=-2=>6%28-2%29-3y=18=>-12-3y=18=>-3y=18%2B12=>-3y=30=>y=30%2F-3=>y=-10
if x=-1=>6%28-1%29-3y=18=>-6-3y=18=>-3y=18%2B6=>-3y=24=>y=24%2F-3=>y=-8
