Answer / Explaination:
First convert each equation into the standard y = mx + b form by solving:
y = -0.5x + 1
y = 4x - 4
Now look at the graphs to see which represents lines of both equations, in this case it is the last one (D).

Answer:
28 points
Step-by-step explanation:
You would insert 8 for b and 12 for l.
SUBSTITUTE
2(8) + (12)
MULTIPLY
16 + 12
ADD
= 28
(I believe I did this right...but I hope this helps. I just got confused on where the l came from, I just thought you mixed up the l and 1.)
