X and Y Intercept Finder
How It Works
This x and y intercept finder uses established formulas to provide accurate results.
The basic rule:
- X-intercept: set y = 0, solve for x → x = c/a
- Y-intercept: set x = 0, solve for y → y = c/b
- Standard form: ax + by = c
Results are estimates. Consult a professional for critical decisions.

How do I find the x-intercept?
Set y = 0 in the equation and solve for x. The x-intercept is where the line crosses the x-axis, so y is always 0 at that point.
How do I find the y-intercept?
Set x = 0 in the equation and solve for y. The y-intercept is where the line crosses the y-axis, so x is always 0 at that point.
Can a line have no x-intercept?
Yes. A horizontal line (like y = 5) never crosses the x-axis, so it has no x-intercept. Similarly, a vertical line has no y-intercept.
