Where are the points?

Answer 2

(1, -5)

(1, 5)

(5, 1)

(-1, 5)

Answer 3

Do you know how to plug them in?

Answer 4

No , I dont.

Answer 5

Okay.. let's take (1,-5). The 1 is x and the -5 is y. So the first equation would look like this -5 <-3(1) + 3

Answer 6

Do you understand how I plugged those numbers in?

Answer 7

Ohhh yes!

Answer 8

You would keep plugging those points in both equations until you got one that made sense in both equations.
