1.
a. Every sweater knitted is approximately $56 earned ($392/7 = $56).
b. Dollars/1 sweater is called the average selling price.
c. This relationship is linear because 0 sweaters knitted results in $0 earned.
2.
a. The constant of proportionality is approximately $16.80 ($504/3 = $168).
b. The equation that represents this graph is y = 16.80x.
c. This is a proportional relationship because the y-intercept is 0 ($0 earned if 0 sweaters knitted).
3.
a. Every minute approximately 83 meters are traveled (747/9 = 83).
b. The equation to show the relationship between x and y is y = 83x.
c. This relationship is linear because the y-intercept is 0 (no distance traveled if 0 minutes).
4.
The company would need to charge a flat rate in addition to the per mile charge. Specifically, they could charge a flat rate of $20 and then $12 per mile.

Apologies for the confusion. The correct answer is:
The company would need to charge a flat rate in addition to the per mile charge. Specifically, they could charge a flat rate of $20 and then $12 per mile.
? 1 is comfusing
I apologize for the confusion in question 1. Let me clarify:
a. Every sweater knitted is a certain amount of dollars earned. To find the amount, we divide the total money earned by the number of sweaters knitted. In this case, the calculation would be:
$392 / 7 = $56
Therefore, every sweater knitted earns approximately $56.
b. Dollars/1 sweater is called the average selling price. In this case, the average selling price is $56.
c. This relationship is linear because for every sweater knitted, there is a constant increase in dollars earned. Additionally, the y-intercept is not 0, so it is not a proportional relationship.
I hope this clarifies question 1 for you.
1Given the table for x, sweater knitted, and y, money earned
a. every sweater knitted is 56 dollars earned
b. dollars/1 sweater is called a unit rate
c this relationship is proportional because 0 sweaters knitted is 0 dollars earned
2 a.the constant of proportonality is 15
b. write an equation that represents this graph y=15x
c this is proportional relationship because the y intercept is 0,0
3shift the graph down 2
4a. every minute traveled is 83 meters traveled
b.write an equation to show the relationship between x and y y=83x
c.the relationship is proportional because the y intercept is 0,0
