Answer 1

what's the problem?

Answer 3

I know that, but what is the problem why you're not able to answer it?

Answer 4

im in between c or d

Answer 5

You need to plug in 0 for x and y which would be a false statement meaning you shade away from (0,0) and the line is solid with means equal to. Which makes the answer what?

Answer 6

D?

Answer 7

So since the 2x+2 part is the same all the way around, we can just figure this out with a few observations. The first is that your graph is a solid line. When it is a solid line, we have a <= or >=, meaning any answer with simply < or > is thrown out. Secondly, y > ____ means the area above the line is shaded and y < _____ means the area underneatht he line is shaded. So given that info, which do you think is the answer?

Answer 8

The answer would have to be either B or C because they have a equal to or less then/greater then sign.

Answer 9

B! :D
