Question

The prediction equation y=1500x+90,000 can be used to model the value of a classic car x years after Mr. Alexander purchased it. Which of the following is the best interpretation of the y-intercept of the linear function?

A) m=1500; The value of the car increases by $1500 each year.
B) m=90,000; The value of the car increases by $90,000 each year
C) b=90,000; The value of the car was $90,000 when Mr. Alexander purchased it.
D) b=1500; The value of the car was $1500 when Mr. Alexander purchased it.

Answer 1

C) b = 90,000; the value of the car was $90,000 when Mr. Alexander purchased it is your answer. The price of the car increases by 1,500 every year (m). But the y intercept (b) is 90,000. Hope this helps!
