What is the definition of CROC (Constant Rate of Change)?

Back

The constant rate of change (CROC) refers to a consistent change in the value of a quantity over time, often represented as the slope in a linear equation.

Front

How do you find the constant of proportionality in a ratio?

Back

To find the constant of proportionality, divide the dependent variable by the independent variable in a proportional relationship.

Front
