x-Intercept
Algebra 1 · Linear Functions
Definition
The x-intercept is the point where a graph crosses the x-axis, where y = 0.
Examples
- For y = 2x - 6, the x-intercept is (3, 0).
- Set y = 0 and solve for x.
Key rule
At the x-intercept the y-coordinate is always 0.
Memory hook
x-intercept: cross the x-axis, y is 0.
