Donovan publishes a magazine of short stories. He keeps track of the number of copies (y) of the magazine he has sold after each of the first x days. After 1 day, Donovan had sold 20 copies of his magazine. After 2 days, he had sold 32 copies of his magazine. He connects these two points with a straight line to estimate his future sales. What is the equation of the line Donovan drew?
Ay-2=12(x - 1)
B y-20= 12(x - 1)
C y-20=12(x - 2)
D y - 32= 12(x - 20)
