Raffle tickets are being sold for a fundraiser. the function  a(n) relates the amount of money raised to the number of tickets sold,  n.  it takes as input the number of tickets sold and returns as output the amount of money raised.  a(n) = 3n  – 15  which equation represents the inverse function  n(a), which takes the money raised as input and returns the number of tickets sold as output?

n (a)=a+15/3 apex

Step-by-step explanation:

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
