<u>Given</u>:
Given that the graph of Bill's Boffo Bagel.
We need to determine the unit rate for Bill's Boffo Bagel.
<u>Unit rate:</u>
The unit rate can be determined using the formula,

Let us substitute any two coordinates that the line passes through the points in the graph.
Substituting the coordinates (2,7) and (4,14) in the above formula, we get;

Simplifying, we get;


Therefore, the unit rate for Bill's Boffo Bagel is $3.5.
Hence, the unit rate is $3.50 for 1 bagel.
Thus, Option b is the correct answer.
The greatest common factor of the three numbers is 4
Please include a picture!!!!
The correct answer is A.
You have direct variation if x and y are modeled by the equation

In this case, m is the constant of proportionality. So, if the constant has to be 2, the equation becomes

A side note: Actually, option C has a constant of proportionality of two as well, except the roles of x and y are interchanged. I chose option A because usually you want the y = mx form, but the names of the variables are obviously meaningless.
Preserved the size because 12inchs is = to 1 ft.
