mathematics distance from origin to axis crossing: the distance from the origin of a coordinate system to the point where a curve or surface crosses an axis
不知道为什么网上查到的教案还特别强调截距不是距离?
OG上说,intercept是坐标,那就是可以为负。
The y-intercept is the y-coordinate of the point at which the graph intersects the y-axis(OG Math Review)
