Answer:
Option a) The initial value of the car is 14,000
Explanation:
we know that
The linear equation into slope intercept form is equal to

where
m is the slope
b is the y-coordinate of the y-intercept
Remember that
The y-intercept is the value of y when the value of x is equal to zero
In this problem we have

so
The slope is equal to

The y-intercept is

therefore
is the value of the car for x=0 (initial value)
