Answer: (24/16)x+3
Explanation: First you have to find your slope so to do that you’ll have to do y1-y2/x2-x1. Once you have your slope you have to put this into an equation and use y=mx+b, so you can use the two first points (8,16) and plug it into the formula. You’ll have 16=3(8)+b once you have that you’ll multiply 3(8) which is 24 and then bring that down so now you have 16=24+b, the next step is to divide 16 by 24 you cannot divide this though because you’ll have a decimal n you don’t want that so you’ll have a fraction of 24/16.

Answer:
He gets 42 visitors 4 weeks after starting to build his website.
He gets 10 new visitors per week.
Step-by-step explanation:
Equation for the number of visitors:
The equation for the number of visitors Timmy's new website receives after t weeks is:

In which b is the number of visitors rightly after he starts.
Timmy is building a new website. Right after he starts, he has 2 visitors.
This means that
, so:

How many visitors does he get 4 weeks after starting to build his website?
This is v(4). So

He gets 42 visitors 4 weeks after starting to build his website.
How any new visitors does he get per week?
After 0 weeks:

After 1 week:

2 weeks:
After 2 week:

22 - 12 = 12 - 2 = 10
He gets 10 new visitors per week.
If I can read the #'s correctly:
add the yes answers together 23+147 = 170
add the no answers together 112+48= 160
so your ratio of haves to have nots is 170 to 160
but both sides can be divided by 10, so it can be simplified to 17 to 16.
Good Luck!
