Answer:

The correct options are 3, 4 and 5.

Step-by-step explanation:

It is given that an air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute.

It means the initial height of air balloon is 1000. So, the y-intercept is (0,1000).

The ball falls at a rate of 50 ft per minute. So, the rate of change is

m=-50

The height of balloon is defined as

h(x)=-50x+1000                      [\because y=mx+b]

Where, x is time in minutes.

The balloon will reach the ground when h(x)=0

0=-50x+1000

50x=1000

x=20

Therefore the options 3, 4 and 5 are correct.
