Answer 1

@iPwnBunnies

Answer 2

The first one.

Answer 3

First, you should be able to figure out the equations of the dotted lines. That's whittle down a few choices.

Answer 4

so its not a or b?

Answer 5

All the y intercepts and x intercepts add up. And they aren't equal to or greater than, so therefore they have a dotted line. To test the direction of the coloured area, you need to sub in the origin and see if it works.

Answer 6

its not a or b, right?

Answer 7

It is A

Answer 8

the answer is a?

Answer 9

Yes.

Answer 10

oh okay I see

Answer 11

Do you understand why?

Answer 12

yes, can you help me with another?

Answer 13

Righto.

Answer 14

its question number 2

Answer 15

It would be B.

Answer 16

did you look at the other options?

Answer 17

The only difference is that the second equation shows that y is lesser than or equal to and the answer A says that the second equation is y is greater than or equal to.

Answer 18

oh okay I get it so if it is > I shade up < down?

Answer 19

it would have to be B. You just need to figure out what direction the coloring will be. For that you substitute y=0 and y=0. If it makes sense, then the graph will color the area that the origin is located.

Answer 20

okay, can you help with another?
