1. What is Slope?

Slope is a measure of the steepness of a line, or a section of a line, connecting two points. It's calculated as 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:

• Rise — The vertical change between two points (unitless)
• Run — The horizontal change between two points (unitless)

Explanation: The slope describes how much the line rises (or falls) vertically for each unit of horizontal movement to the right.

3. Importance of Slope Calculation

Details: Slope is fundamental in mathematics, physics, engineering, and many other fields. It's used to describe rates of change, gradients, and inclines in various applications from road construction to graph analysis.

4. Using the Calculator

Tips: Enter the rise and run values. The run cannot be zero (as division by zero is undefined). Values can be positive or negative (except run which must be non-zero).

5. Frequently Asked Questions (FAQ)

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

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

Q3: What does a slope of zero mean?
A: A slope of zero means the line is perfectly horizontal.

Q4: What if the run is zero?
A: If run is zero, the line is vertical and the slope is undefined (infinite).

Q5: How is slope used in real life?
A: Slope is used in construction (ramps, roofs), road design, wheelchair accessibility, physics (velocity), economics (marginal rates), and many other applications.
