The answer is B

Step-by-step explanation:

1)

These are in Y = MX + B form

The first line has a positive slope, so the coefficient "M" is positive.

The second line has a negative slope, so the coefficient "M" is negative.

2)

The first line has a filled in dot at Y = 2.

Since it's to the left (less than X direction)...

X <= 0

The second has an empty circle at Y = 4.

Since the line goes to the right

0 < X

3)

Also, the "+2" and the "+4" in the equation as the "+ B" indicates where each line will cross the Y axis.

From these things, we can infer that B is the correct answer.
