B should be the only correct answer.
Answer:

Step-by-step explanation:
If it has a slope of 3/4, then it will look like this:

If it passes through (4, 0), than y = 0 when x = 4



Therefore, the equation is
.
Answer:
-9/7
Step-by-step
Slope Formula:

We can plug in the numbers 7 and -2 for the y and -4 and 3 for x

Got it. Hope this will help.
