Question: The distance d, in miles, that a small plane is from its destination is represented by the function \[d(t)=250-100t\], where t is the time, in hours, remaining for the flight.

a) What is the slope of this function? Write a sentence that explains the real-world meaning of this slope.

b) What is the value of d when t equals zero (or the ‘y-intercept’ of this function)? Write a sentence that explains the real-world meaning of this distance.

c) What is the value of t when d equals zero (or the ‘x-intercept’ of this function)? Write a sentence that explains the real-world meaning of this time.
