Final answer:
The slope of a tangent line calculator can determine the rate of change at a specific point on a curve.
Step-by-step explanation:
The slope of a tangent line calculator can be used to calculate the slope of a straight line tangent to a curve at a given point. To find the slope, follow these steps:
- Identify the tangent line by finding the line that touches the curve at the desired point.
- Determine the coordinates of two points on the tangent line. These points should be close to the desired point.
- Calculate the slope of the line using the formula: slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.
