Answer:
The equation of the line would be y = -1/2x + 3. You can use this to make a graph that looks like this:
G; Whatever point is in a 180 degree reach of the direction the angle is in is the interior. Think about it like a clock that can only reach for one side, up or down, of the 3 and 9. Whichever direction it is angled towards is the one you look in.
8.5x + 9x = y
That is because you don't know how many hours they worked, so you can't how much money they made.
If you plugged in 4 hours for the x's you'll do something like this:
8.5 (4) + 9 (4) = y
34 + 36 = y
70 = y
That is how you would do it if you have the number of hours they worked.
