Andrew purchased a 1985 Jaguar XJS for $20,000. When he told his wife, she kindly let him know that after one year, his car will only be worth $18,000. In fact, the value of his car will decrease by $2,000 every year.
Andrew graphed the value of his car using a line. The x-axis represents the number of years he owns the car. The y-axis represents the value of his car.
He plots the two points (0,20000) and (1,18000). He then realizes the x-intercept will tell him when his car will be worth $0.
What is the x-intercept of the line Andrew is graphing?
How many years will it take for the car to be worth $0?
No need for explanation. Just need answers. Thanks!
