Suppose you bought a used car for $15,000 a few years ago, and its value has been decreasing at the rate of $1,000 per year since then. Find the y intercept of the graph and explain what it means. (Remember, the y intercept is a point, not a number.)
a. (0, 1,000); The car's value is decreasing by $1,000 per year.
b. (15, 0); The car will be worthless in 15 years.
c. (0, 15); The car is 15 years old.
d. (0, 15,000); The value of the car at the time you bought it was $15,000.
