Question

5. Zhao purchased a used car for $11,500. This make and model used car

straight line depreciates to zero after 9 years. (a) Identify the coordinates
of the x and y intercepts. *

Answer 1

(9, 0)

(0, 11200)

Explanation:

The x - intercept is the value of x when y = 0 ; similarly, the y - intercept is the value of y, when x = 0

From the given relation :

y = price, x = number of years

Price after 9 years of usage, the price of car is depreciated to 0

Hence,

x = 9, y = 0

(9, 0)

At purchase, the value of car is 11,200 ;

At this price, the number of years of usage of car is 0

Hence ;

x = 0 ; y = 11200

(0, 11200)
