This graph shows the value of Jessica's vehicle at different years after she purchased it. Which answer is the best estimate for the average rate of change between year 0 and year 3

A. -$6300/year
B. -16000/year
C. -$5300/years
D. -$4000/year​

B

it goes down by $16,000 in that time frame

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

what
