Answer 2

Use elimination to find the intercepts.

y < -3x + 3
y < 3(x + 2)

y < -3x + 3
y < 3x + 6

Does that help?

Answer 3

not really , :/

Answer 4

Have you learned elimination yet?

Answer 5

no

Answer 6

may i just have the answer ?

Answer 7

Well then why don't you just graph it and find the interception?

Answer 8

The link I put above is really easy. Try it and see with coordinates work.
