Slope is 2/3 so formula is y+1=⅔(x-8)
y+1= ⅔x-16/3
multiply thru by 3 to get 3y+3=2x-16
simplify too get 2x-3y=16
The answer to this question would b:
=5x−9

Answer:
900 large boxes were sold, and 750 small boxes.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of large boxes of cookies sold.
y is the number of small boxes of cookies sold.
A total of 1,650 boxes of Girl Scout cookies were sold last week.
This means that
![x + y = 1650](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%201650)
So
![x = 1650 - y](https://tex.z-dn.net/?f=x%20%3D%201650%20-%20y)
Each large box cost $3.50 and each small box cost $2.00. The Girl Scout group earned $4,650.
This means that
![3.5x + 2y = 4650](https://tex.z-dn.net/?f=3.5x%20%2B%202y%20%3D%204650)
Since ![x = 1650 - y](https://tex.z-dn.net/?f=x%20%3D%201650%20-%20y)
![3.5(1650 - y) + 2y = 4650](https://tex.z-dn.net/?f=3.5%281650%20-%20y%29%20%2B%202y%20%3D%204650)
![5775 - 3.5y + 2y = 4650](https://tex.z-dn.net/?f=5775%20-%203.5y%20%2B%202y%20%3D%204650)
![1.5y = 1125](https://tex.z-dn.net/?f=1.5y%20%3D%201125)
![y = \frac{1125}{1.5}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1125%7D%7B1.5%7D)
![y = 750](https://tex.z-dn.net/?f=y%20%3D%20750)
![x = 1650 - y = 1650 - 750 = 900](https://tex.z-dn.net/?f=x%20%3D%201650%20-%20y%20%3D%201650%20-%20750%20%3D%20900)
900 large boxes were sold, and 750 small boxes.
