What is a constant rate of change?

Back

A constant rate of change refers to a situation where the change in one quantity is consistent with the change in another quantity over time, often represented as a linear relationship.

How do you calculate the rate of change?

Back

The rate of change is calculated by dividing the change in the dependent variable by the change in the independent variable, often expressed as (y2 - y1) / (x2 - x1).

How can you express a constant rate of change in an equation?

Back

A constant rate of change can be expressed in the form of a linear equation, typically y = mx + b, where m is the slope (rate of change) and b is the y-intercept.

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of the dependent variable when the independent variable is zero.

How do you determine the constant rate of change from a table of values?

Back

To determine the constant rate of change from a table, calculate the difference in the dependent variable divided by the difference in the independent variable for any two points.
