Is there a proportional relationship between number of sandwiches and the cost of the order? Explain how you know.
(The picture shows what the relationship is now all I need to find is if it’s proportional or not, and why. Can you help me please? It’s homework, and it’s due in 5 minutes.)

Answer 1

• No, there is no proportional relationship

Explanation:

The proportional relationship is:

• y = kx, which is a special form of linear equation, with zero y-intercept

In the given case we have:

• y = 4.5x + 10

This is a linear function but not proportional relationship because it has y-intercept, different than zero
