A jet travels 4928 miles against the wind in 7 hours and 5628 miles with the wind in the same amount of time. What is the rate of the jet in still air and what is the rate of the wind?​

just sum

10 + 10 = 20

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
