Drawing a Conics Graph

Drawing a Hyperbola

A hyperbola can be drawn with either a horizontal or vertical orientation. The hyperbola type is determined by the direction of its principal axis.

kDrawing a Hyperbola that Opens Horizontally

The standard form of a hyperbola with a horizontal axis is: (x – H)2 – (y – K)2 = 1.
