A town determined that the function f(x) = 820(0.97)* models the number of speeding tickets issued in the town x years after 2000. true about the number of speeding tickets issued each year?
A
The number of tickets is decreasing by 3% each year.
B) The number of tickets is decreasing by 97% each year.
The number of tickets is increasing by 3% each year.
The number of tickets is increasing by 97% each year.

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

i got 10.28 but that rounds up to 10.3
