The term x-intercept refers to the x-coordinate of the point at which a graph in the xy-plane intersects the x-axis. The term y-intercept is used analogously. Sometimes the terms x-intercept and y-intercept refer to the actual intersection points.
术语 x-截距指的是 xy 平面上的曲线相较于 x-轴的点的 x 坐标值。术语 y-截距有类似定义。有时候术语 x-截距和 y-截距也表示曲线与坐标轴相交的那个点。
