## Definition Of X-Intercept

The x-intercept of a line is the point at which the line crosses the x-axis.

The y-coordinate of the point where a line intersects the x-axis is 0
So, the x-intercept of a line can also be found by substituting y = 0 in the equation of the line.

### Examples of X-Intercept

As the line shown in the graph is intersecting the x-axis at the point (-3, 0), so the x-intercept of the line is -3.
