I NEED HELP ASAP Please do step by ste and tell me where it goes thank you

Step-by-step explanation:

A: 5600 meters per hour

B: 700 meters per 1/6 hour

C: 4200 meters per hour

I cant see the final question

5600 meters per hour

700 meters per 1/6 hour

7200 meters per hour  

Step-by-step explanation:

It must have the same slope as the given line, so

m = -A/B = -1/-2 = 1/2

So far, we have

y = mx + b = x/2 + b

Use the given point to find b.

4 = -2/2 + b = -1 + b

b = 5

y = x/2 + 5

Multiply through by 2.

2y = x + 10

Standard form:

x - 2y = -10
