Answer 1

See the overlapped region in this graph?

The overlapped part has all the points that are solutions to that system of inequalities..so which points are in that overlapped region?

Answer 2

Remember, it can't be in the red only or the blue only. Just where the red and blue overlap.

Answer 3

C & D ?

Answer 4

No, D is on the dotted line of the blue graph.

If a point is on a DOTTED line, it is not a solution, but if it's on a SOLID line, it IS a solution.

In this case, it's on a dotted line and a solid line, but it doesn't matter because it's on a dotted line too.

(2, 4)

y < 4

Plug in 4 for 'y':

4 < 4

This is not true..that's why it is incorrect.

C is correct though.

Answer 7

B =)

Answer 8

Correct! :)
