Someone please be nice and help please:)

0,0 means 0 milkshakes and 0  a. yes, because in the graph the line is a linear function, and also because the price of a milkshake would not change, so it is constant.

b. It means that they have not sold any milkshakes yet, therefore they have made no money

c. $1.50 per milkshake

d. (10,15)

6.In a graph, the points (1, r) and (0,0) must appear on the line of the proportional relationship. ... If a graph of a line passes through the origin and contains the point (1, r), r representing the unit rate, then the relationship is proportional.

Step-by-step explanation:

a. Yes, because in the graph the line is a linear function, and also because the price of a milkshake would not change, so it is constant.

b. It means that they have not sold any milkshakes yet, therefore they have made no money

c. $1.50 per milkshake, or "r"=1.5

d. (10,15)

6. "r" represents the unit rate so if a graph of a line passes through the origin (0,0) and contains the point (1, r), r representing the unit rate, then the relationship is proportional

Step-by-step explanation:

I think these are correct. Hope they help, and have a great day!

ummm seems that u didnt post the attachement !
