Slope Formula:
From: | To: |
The slope formula calculates the slope (m) of a line from the standard form equation ax + by + c = 0. The slope represents the steepness and direction of the line.
The calculator uses the slope formula:
Where:
Explanation: The formula converts the standard form equation to slope form, where the slope is calculated as the negative ratio of the x-coefficient to the y-coefficient.
Details: Calculating slope is fundamental in coordinate geometry, physics, engineering, and economics. It helps determine the rate of change, direction of lines, and relationships between variables.
Tips: Enter coefficients a and b from your equation in standard form (ax + by + c = 0). Ensure b is not zero to avoid division by zero error.
Q1: What if my equation is not in standard form?
A: Convert your equation to standard form (ax + by + c = 0) first before using the coefficients in this calculator.
Q2: What does a slope of zero mean?
A: A slope of zero indicates a horizontal line, meaning there is no change in y as x changes.
Q3: What does an undefined slope mean?
A: An undefined slope occurs when b = 0, indicating a vertical line where x is constant.
Q4: Can I use this for non-linear equations?
A: No, this formula only applies to linear equations in standard form.
Q5: How does the sign of the slope affect the line?
A: A positive slope indicates the line rises from left to right, while a negative slope indicates it falls from left to right.
