Aplane is descending into the airport. after 5 minutes it is at a height of 6500 feet. after 7 minutes it is at a height of 5900 feet. write an equation to model its height after t minutes. when will it land assuming the airport is at 0 feet.

Let's assume

height of plane  in feet =h

time in minutes =t

we are given

A plane is descending into the airport. After 5 minutes it is at a height of 6500 feet

so, we get one point as (5,6500)

After 7 minutes it is at a height of 5900 feet

so, we get another point as (7,5900)

we can use point slope form of line

points as

(5,6500)

x1=5, y1=6500

(7,5900)

x2=7 , y2=5900

Calculation of slope(m):

now, we can plug values

Equation of line:

we can use formula

we can plug values

Time of landing:

we can set h=0

and then we can solve for t
