I believe it is A
Because his initial starting point is 12 and then 1.5x to increase and reach his goal of 26
In (5,0), five represents how many times he will move over in the X axis. Since it’s zero, you do not move at all. However you will move five spot up, because the five is on the Y axis. Then, he will do the same thing with your second pair of coordinates. You do not move on the X axis, but you will move two spots down on the Y axis. Then, trace your pencil between the two dots. You will notice that it passes seven intersections, so your answer will be seven units.
Answer:

Step-by-step explanation:

The correct answer is B. I figured this out by testing out coordinates into each equation. I am only going to show my work for equation B though... if you want to see the rest of my work, message me.
(0,0) ⇒ this point is within the shaded part of the graph
0 ≤ 1/2(0) + 3
0 ≤ 0 + 3
0 ≤ 3
True
(1,4) ⇒ this point is within the unshaded region
4 ≤ 1/2(1) + 3
4 ≤ 1/2 + 3
4 ≤ 3.5
False
This proves that equation B matches the graph shown.
