Proportional Relationships

A set of flashcards covering key vocabulary related to proportional relationships, helping the student understand fundamental concepts and their applications.

Proportional Relationship

A relationship where two amounts change at the same rate, maintaining the same ratio.

Unit Rate

The ratio that shows how much of one quantity corresponds to a single unit of another quantity.

Slope

The steepness of a line on a graph, indicating the rate of change between two quantities.

Constant of Proportionality

The constant factor (k) that relates two proportional quantities in the equation y = kx.

Origin

The point (0, 0) on a graph where both quantities are zero; all proportional relationships pass through this point.

Equation of a Proportional Relationship

An equation that shows how two quantities are related in a proportional manner, typically in the form y = kx.

Graph of a Proportional Relationship

A straight line that starts at the origin and shows the relationship between two proportional quantities.

Ratio

A relationship between two quantities, showing how many times one value contains or is contained within the other.

Predict and Calculate

The ability to estimate future outcomes or total amounts based on existing proportional relationships.

Real World Applications

Practical situations, such as cooking, shopping, and scientific measurements, where proportional relationships are utilized.
