Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other quantity is constant.

Front

How do you find the constant of proportionality from a table?

Back

The constant of proportionality (K) can be found by dividing the value of one quantity by the corresponding value of the other quantity in a proportional relationship.

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together, expressed as a quantity of one per one unit of the other.

Front

What does the equation y = kx represent?

Back

This equation represents a direct variation where y varies directly with x, and k is the constant of proportionality.

Front

How can you identify a proportional relationship on a graph?

Back

A proportional relationship on a graph is represented by a straight line that passes through the origin (0,0).

Front

What is the significance of the slope in a proportional relationship?

Back

The slope of the line in a proportional relationship represents the constant of proportionality (K).

Front

If K = 2, what does this mean in a proportional relationship?

Back

If K = 2, it means that for every unit increase in x, y increases by 2 units.

Front

How do you convert a ratio to a unit rate?

Back

To convert a ratio to a unit rate, divide both terms of the ratio by the second term.

Front

What is the formula to find the unit rate from a total quantity?

Back

The formula to find the unit rate is: Unit Rate = Total Quantity / Number of Units.

Front

What is the relationship between a table of values and a linear equation?

Back

A table of values can represent the solutions of a linear equation, where each pair of values corresponds to a point on the graph of the equation.
