The slope of the tangent line at a specific point on a curve represents the instantaneous rate of change or the steepness of the curve at that point.
Derivative: The derivative is a function that gives you the slope of the tangent line at any point on a curve.
Average Rate of Change (Secant Line): The average rate of change between two points on a curve is represented by the slope of the secant line connecting those two points.
Instantaneous Rate of Change: Similar to slope of the tangent line, it refers to how quickly something is changing at an exact moment in time.
