where the graph intersects the x-axis; the value of is 0, a point of the form

The x-coordinate of the point where the line crosses the x-axis

The point where a graph intersects the x-axis.

The distance from the origin to the point at which a curve cuts the x-axis (horizontal axis).

a point on the x-axis (a,0).

For linear or semi-log graphs, the value of the abscissa (horizontal) coordinate of a graph when the ordinate (vertical) is zero. For log-log graphs, the value of the abscissa when the ordinate equals 1. It has the units of the abscissa. See slope, Intercept, Y-intercept.
