Understanding Rate Of Change

Rate of change refers to how quickly one quantity changes compared to another quantity.

For example:

• Speed measures change in distance over time.
• Profit growth measures change in income over months or years.
• Temperature changes can be measured over hours or days.

A positive rate indicates growth or increase, while a negative rate indicates decline or decrease.

---

Understanding Slope

Slope is one of the most common forms of rate of change in mathematics.

It measures how steep a line is between two points on a graph.

The slope can be:

• Positive
• Negative
• Zero

A positive slope means values are increasing.
A negative slope means values are decreasing.
A zero slope means no change.

The calculator automatically identifies the direction for users.
