The volleyball team at West View High School is comparing T-shirt companies where they can purchase
their practice shirts. The graph represents the two
companies' prices. What is the linear equation that
represents each T-shirt company?
Shirt Box: y = 7.5x + 30
Just Tees: y = 10.5x
I have the answers these are them above.
Just wanted to help anyone else out that has trouble finding them.

Question:

The graph represents the two companies' prices. What is the linear equation that represents each T-shirt company?

1.) Shirt Box: y = 7.5x + 30

2.) Just Tees: y = 10.5x

Step-by-step explanation:

For Number -One- We do - 7.5 + 30 = 37.5

For Number -Two- We do -  10.5  ×  "X"

You See We have to solve for "X"

This is just to give the idea, and Kinda help Explain it. . .

(Yes i know im 4 days late - & Yes i know its already answered, But I just explained it To get the Understanding of the Two answers.)

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

b
