Answer 4

So there are two lines. First, what is the equation for the dotted line if you imagine it's solid

Answer 5

dk

Answer 6

It would be x = -2

Answer 7

so now we know its either b or c?

Answer 8

c is my guess

Answer 9

Yeah we know it's not B

Answer 10

What if it is B? How do you know it's not B?

Answer 11

And since it's a dotted line it has to be x<-2 and not less than or equal to.

Answer 12

Well we established the line as x = -2, so it can't be x < -3

Answer 13

Yes C is correct.

Answer 14

The vertical dotted line is x = -2.
The region to the left of this line is x < -2.
The dotted line signifies that the line itself is not included in the region.
So x < -2 (not x ≤ –2).

The solid diagonal line is y = -x - 2.
The region below and to the left of this line is y < -x - 2.
The solid line signifies that the line itself is included in the region.
So y ≤ –x – 2.

Answer:
x < –2; y ≤ –x – 2

Answer 15

thanks guys

Answer 16

What did you learn from posting this question? Do you know which are solid lines and which are dotted lines?

Answer 17

As in this way: \[\le, \ge, <, >, \]
