You can put this solution on YOUR website! 33.
4x-y=7
-y=-4x+7
y=4x-7
a,b,&c are on this line.
 (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = 4x -7).
-------------------------------------------------------------------------
34.
2x/5y=6 cross multiplying we get:
30y=2x
y=2x/30
y=x/15
 (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = x/15).
I must be misinterpreting the formula because I get no answers to match the choices given.
