Slope: Slope measures how steep or flat a line is by comparing vertical change (rise) with horizontal change (run). It's represented by m in y = mx + b.
Tangent Line: A tangent line touches a curve at exactly one point and has the same slope as that point on the curve.
Instantaneous Rate of Change: The instantaneous rate of change refers to the rate of change at a specific point on a curve. It's like finding out your speed at an exact moment while driving.
