For the <line> element, this attribute define the y-axis coordinate of the start of the line. If the attribute is not specified, the effect is as if a value of 0 were specified.
For the <linearGradient> element, this attribute define the y-axis coordinate of the start of the vector gradient onto which the <stop> elements are mapped. If the attribute is not specified, the effect is as if a value of 0% were specified.

  A <coordinate> is a length in the user coordinate system that is the given distance from the origin of the user coordinate system along the relevant axis (the x-axis for X coordinates, the y-axis for Y coordinates). Its syntax is the same as that for <length>. Within the SVG DOM, a <coordinate> is represented as an SVGLengthor anSVGAnimatedLength.
