Answer:
C
Step-by-step explanation:
You can rearrange the equation to make it: 4y=3x-2
The slope right now is 3,but that's not the answer
So you divide the whole equation by 4 (it will give you: y=3/4 x- 0.5
So from that you can see that the slope is 3/4, C
The answer should be -3, I can explain it if you want.
It would depend on how large the rectangle is
1 mi = 5280 ft
1 h = 3600 s
therefore:

Answer: 31.8 mi/h = 46.64 ft/s
