y = 3x

(0, ____) (-1,____) (7,____)


0, -1, and 7 represent x values. To find the corresponding y values, simply plug in those values for x into the original equation.

1. Start with y+=+3x

Plug in 0 y=3%280%29

Simplify y=0 So when x=0, y=0. (0,0)


2. Start with y+=+3x

plug in -1 y=3%28-1%29

Simplify y=-3 So when x=-1, y=3. (-1,-3)


3. Start with y+=+3x

Plug in 7 y=3%287%29

Simplify y=21 So when x=7, y=21. (7,21)



Solutions: (0,0) (-1,-3) (7,21)
