What is the slope of a linear function?

Back

The slope of a linear function represents the rate of change of the dependent variable with respect to the independent variable, calculated as the rise over run.

Front

What is a linear relationship?

Back

A linear relationship is a relationship between two variables that can be represented by a straight line on a graph, characterized by a constant rate of change.

Front

What is the significance of the initial value in a linear model?

Back

The initial value in a linear model is the starting point of the dependent variable when the independent variable is zero, represented by the y-intercept.
