What is the definition of rate of change?

Back

The rate of change is a measure of how a quantity changes in relation to another quantity, often expressed as a ratio or a derivative.

How do you calculate the rate of change between two points on a graph?

Back

The rate of change can be calculated using the formula: (change in y) / (change in x) or (y2 - y1) / (x2 - x1).

What does a negative rate of change indicate?

Back

A negative rate of change indicates that as one quantity increases, the other quantity decreases.

Front

What does a positive rate of change indicate?

Back

A positive rate of change indicates that as one quantity increases, the other quantity also increases.

In the equation y = mx + b, what does 'm' represent?

Back

In the equation y = mx + b, 'm' represents the slope of the line, which is the rate of change of y with respect to x.
