The slope is -3/1 so to find other points, go to (2,-1) and go down 3, over 1.
        
             
        
        
        
Answer:
Revenue = 1380
Step-by-step explanation:
Given:
Revenue means the sales or turnover of a company when it sells its products. In other words, it is nothing but the income of a company on selling the products.
Here, the company is selling backpacks. So, revenue is the amount earned by the company on selling 'x' backpacks. The linear model to represent the same is given below.
The revenue received from selling 'x' backpacks is given as:

Number of backpacks sold (x) = 40 
Now, in order to find the revenue received on selling 40 backpacks, we need to plug in 40 for 'x' in the equation above and solve for the revenue, 'R'.
On plugging 40 for 'x', we get:

Therefore, the revenue received by the company on selling 40 backpacks is 1380.
 
        
             
        
        
        
X varies directly as y
x = ky
3 = 2k
k = 

 when x =9
9 = 

y

 = y
∴y = 6

Answer:
y = 12x
Step-by-step explanation:
-1 times 4 equals -4 so you have -4,y = 3x + 5 so you do 5 + 3 so it is 8x then you have -4,y = 8x so you add 4 to each side and it becomes y = 12x
