Please Help Me This Is For My Mid-Term I Give You 50 points

100 miles (A)

Step-by-step explanation:

determine where the lines intersect.

The Domain is the left most part of the line to the right most part of the line (the most negative x, to the most positive x). 

The Range is the bottom most part of the line to the top most part of the line (the most negative y, to the most positive y).

Domain - [0,12]
Range - [-2,4]
It starts decreasing at (0,4) and stops decreasing at (3,-2)

Hope I helped!
