The percent of homes with digital TV services, which stood at 5% at the beginning of 1999 (t = 0) was projected to grow linearly so that at the beginning of 2002 (t = 3) the percentage of such homes was projected to be 14%.

(a) Derive an equation of the line to determine y (the percentage of homes with digital TV service) based on t, passing through the points

A(0, 5) and B(3, 14).

y =

(b) Plot the line with the equation found in part (a)

(c) Using the equation found in part (a), find the percentage of homes with digital TV services at the beginning of 2001. %
