What is the definition of the "constant of proportionality" in a proportional relationship?

• The ratio of the dependent variable to the independent variable.

• The difference between the dependent variable and the independent variable.

• The sum of the dependent variable and the independent variable.

What is a "scale drawing"?

• A drawing that uses a scale to represent an object as smaller or larger than the actual object.

• A drawing that shows the actual size of an object.

• A drawing that uses different colors to represent different values.
