The x-intercept is the point on the x-axis where the line crosses it. The y-coordinate of the line's x-intercept is always zero. The x-coordinate of the x-intercept is the number where it crosses the x-axis. A line with an x-intercept of (5,0) crosses the x-axis at the number 5. A line with an x-intercept of (-5,0) crosses the x-axis at -5. Which of these coordinates could be a line’s x-intercept?
