Exploring Proportional and Nonproportional Relationships

What does it mean for a relationship to be proportional?

• It always decreases.

• It always increases.

• It follows a specific pattern.

• It increases or decreases by a constant rate.

Which of the following is NOT a method to determine if a relationship is proportional?

• Comparing the ratios of y to x.

• Observing if it follows a pattern.

• Ensuring it goes through the point (0,0).

• Checking if the fractions are equivalent.

If a relationship goes through the point (0,0), what can be inferred?

• It follows a pattern.

• It is proportional.

• It is non-proportional.

• It is increasing.

Which of the following fractions is equivalent to 1/3?

• All of the above

• 2/6

• 3/9

• 4/12

Why is the relationship 1/50, 2/70, 3/90, 4/110 considered non-proportional?

• It decreases over time.

• The fractions are not equivalent.

• The pattern is not consistent.

• It does not go through (0,0).

What is the reduced form of the fraction 2/70?

• 1/25

• 1/50

• 1/30

• 1/35

If a relationship does not go through (0,0), what can be concluded?

• It is non-proportional.

• It is proportional.

• It is increasing.

• It follows a pattern.

What is the cost of one pound of meat if 2.5 pounds cost $7.20?

• $2.50

• $3.00

• $2.88

• $2.72

How much would 4 pounds of meat cost if 1 pound costs $2.88?

• $11.00

• $11.52

• $10.00

• $12.00

What is the equation relating the cost to pounds of meat if 1 pound costs $2.88?

• Cost = pounds / 2.88

• Cost = 2.88 * pounds

• Cost = 2.88 / pounds

• Cost = 2.88 + pounds
