Exploring Proportional and Nonproportional Relationships

What is the main focus of today's lesson?

• Identifying proportional and non-proportional relationships

• Learning about algebraic expressions

• Studying historical events

• Understanding geometric shapes

Which of the following is a method to determine if two quantities are proportional?

• Adding them together

• Dividing them and checking for a constant ratio

• Checking if they are prime numbers

• Subtracting one from the other

What is the constant of proportionality abbreviated as?

• COE

• COP

• COR

• COT

How do you determine if a relationship in a table is proportional?

• By dividing y by x and checking for consistency

• By subtracting y from x

• By multiplying the x and y values

• By adding the x and y values

If y divided by x is consistent across a table, what can we conclude?

• The relationship is non-proportional

• The relationship is proportional

• The relationship is linear

• The relationship is undefined

What is the constant of proportionality if y = 2x?

• 0.5

• 4

• 1

• 2

In a non-proportional relationship, what is missing?

• A variable

• A constant of proportionality

• An equation

• A table

If Alina earns $7 per hour babysitting, how much does she earn in 3 hours?

• $28

• $35

• $21

• $14

What is the cost of a pizza with 2 toppings if the base price is $10 and each topping costs $1.50?

• $12.50

• $13.50

• $13.00

• $11.50

Why is the relationship between the number of toppings and the total cost of the pizza non-proportional?

• Because the base price is added to the cost of toppings

• Because the toppings are free

• Because the base price is subtracted from the cost of toppings

• Because the cost of toppings decreases with each additional topping
