Equation of a Line with Given Intercepts Calculator
Introduction & Importance
An equation of a line with given intercepts is crucial in mathematics, physics, and engineering. It allows us to represent a straight line on a graph using a mathematical equation. This calculator helps you find the equation of a line given its intercepts on the x and y axes.
How to Use This Calculator
- Enter the x-intercept (where the line crosses the x-axis).
- Enter the y-intercept (where the line crosses the y-axis).
- Click “Calculate”.
Formula & Methodology
The formula for the equation of a line with given intercepts (a, b) is:
y = mx + b
Where ‘m’ is the slope of the line, calculated as:
m = (y2 – y1) / (x2 – x1)
Given x1 = a and y1 = b, the equation becomes:
y = (y – b) / (x – a) * x + b
