The x-intercept is the point where a graph crosses the x-axis. At this point, the value of y is always zero. To find the x-intercept of a linear equation, you can set y to zero and solve for x. This helps in understanding the behavior of the graph and its relationship with the x-axis. In a coordinate system, the x-intercept is represented as an ordered pair, typically written as (x, 0) . For example, in the equation of a line, if you find that the x-intercept is at (3, 0), it means the line crosses the x-axis at x = 3.
