A parachutist jumps from an airplane and immediately opens her parachute.
Her altitude, h, in metres after t seconds is modelled by the equation
h(t) =- 41+ 300. A second parachutist jumps 5 seconds after the first
parachutist jumps. Her altitude, in metres, during this time is modelled by the
equation h(t) =- 4.9(1 - 5)2 + 300. When are the both parachutists at the same
height when falling?
[4A)

ratio is 2 : 9

the answer is three

13.5 : 3

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. : )
