1. What is Slope?

Slope is a measure of the steepness of a line, representing the ratio of the vertical change (rise) to the horizontal change (run) between two points on a line.

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

• \( x_1, y_1 \) — Coordinates of the first point
• \( x_2, y_2 \) — Coordinates of the second point

Explanation: The formula calculates the rate of change between two points, indicating how much y changes for each unit change in x.

3. Importance of Slope Calculation

Details: Slope is fundamental in mathematics, physics, engineering, and economics. It helps determine the direction and steepness of lines, rates of change, and is essential in calculus for finding derivatives.

4. Using the Calculator

Tips: Enter the coordinates of two points. The calculator will compute the slope. If the line is vertical (x1 = x2), the slope is undefined.

5. Frequently Asked Questions (FAQ)

Q1: What does a positive slope indicate?
A: A positive slope indicates that the line rises as it moves from left to right.

Q2: What does a negative slope indicate?
A: A negative slope indicates that the line falls as it moves from left to right.

Q3: What is a zero slope?
A: A zero slope indicates a horizontal line, where y-values remain constant as x changes.

Q4: When is slope undefined?
A: Slope is undefined for vertical lines, where x1 = x2, because division by zero is undefined.

Q5: How is slope used in real-world applications?
A: Slope is used in various fields: calculating gradients in civil engineering, determining velocity in physics, analyzing trends in economics, and more.
