Understanding Proportional Relationships

What is a key characteristic of a proportional relationship?

• The ratio between variables changes.

• The ratio between variables is constant.

• The variables are unrelated.

• The variables are always equal.

In the example where X is 1 and Y is 1.2, what is the constant ratio of Y to X?

• 2.0

• 1.2

• 1.0

• 0.8

What happens to the value of Y when X is multiplied by the constant ratio in a proportional relationship?

• Y decreases.

• Y remains the same.

• Y is multiplied by the constant ratio.

• Y is divided by the constant ratio.

How can you identify a proportional relationship on a graph?

• The points form a zigzag pattern.

• The points are scattered randomly.

• The points form a straight line through the origin.

• The points form a circle.

What is the significance of the zero point in a proportional relationship?

• It shows where the line starts.

• It indicates the maximum value.

• It confirms the line passes through the origin.

• It is irrelevant to the relationship.
