Constant of Proportionality Review

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities, expressed as y = kx.

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

Back

To find the constant of proportionality from a table, divide the value of y by the corresponding value of x for any pair of values.

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship is in the form y = kx, where k is the constant of proportionality.

If y = 18.50x, what is the constant of proportionality?

Back

The constant of proportionality is 18.50.

Front

What does it mean if a relationship is not proportional?

Back

If a relationship is not proportional, it means that the ratio of y to x is not constant.

Front

How do you calculate the unit cost?

Back

To calculate the unit cost, divide the total cost by the number of units.

Front

If 15 pizzas cost $97.50, what is the unit cost per pizza?

Back

The unit cost per pizza is $6.50.

Front

What is the constant of proportionality for $9 per hour?

Back

The constant of proportionality is $9, meaning for every hour, the cost is $9.

Front

What is the formula to find the total cost in a proportional relationship?

Back

The formula to find the total cost is Total Cost = k * Number of Units.

If k = 25, what does this imply about the relationship?

Back

If k = 25, it implies that for every unit, the cost is $25.
