Apilot wants to arrive at her destination as soon as possible. air traffic is busy, so she can take off 16 minutes later than expected and will be able to travel four times faster than expected if she waits. create an equation to represent her total travel time, including wait time, where x is the number of minutes the flight was expected to take.

Step-by-step explanation:

Let x be the number of minutes the flight was expected to take. Actually, the flight will take (x+16) minutes.

Let S be the distance to be covered.

Expected speed

Actual speed (shee will be flying 16 minutes less)

The pilot will be able to travel four times faster than expected if she waits, so

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
