In mathematics and geometry, the y-coordinate or vertical line showing height in a coordinate system.
From Latin applicatus (applied, fitted), from applicare (to apply). Coined in mathematical terminology to describe the axis you 'apply' vertically on a graph.
The applicate is one of three dimensions mathematicians use to locate points in space—abscissa (x), applicate (y, the applied vertical line), and z-axis for depth; the word 'applicate' literally means 'the thing you apply' because you apply it perpendicular to the horizontal baseline.
