Answer:
box 1 and 4.
Step-by-step explanation:
To find the slope of the line, you use the slope formula (y2-y1)/(x2-x1).
Plugging in the points for line a would give you (20.25-14.5)/(3-2), which gets you a slope of 5.75.
Doing the same for line b would get you a slope of 5.5. As you can see, box 1 and box 4 are correct.
