y = 2x - 6

x + y = 6

2x - y = 9

6x + 3y = 15

y > 2x - 3

y < 5 - x (this < has a line under it, and yes I know what they mean)

2x + y < 4 (This < has a line under it)

x - y < - 2

-2 < y < 3 (both have lines under them)

1 < x < 4

y < 5 (has a line under it)

y < x + 3

y > 2x (has a line under it)

y > x + 3

y - x > 5 (has a line under it)

y - 2x < 7 (has a line under it)

-5 < x < -1 (both have lines under them)
