Conic by Directrix, Focus Point

Conic by Five Points

Cubic Function by Four Points

Conic Arc by Five Points

The lines constructed through the intersections of two conics. This is also defined for non intersecting conics.

Hyperbola by Focuses Point

Cubic Curve by Nine Points

Equilateral Hyperbola by Four Points

Directrix of a Conic

The directrix line of a conic.

Asymptotes of a Hyperbola

A curve's a curve, a plane's a plane, and the two won't mix.

A hyperbola constructed by its focuses and a point that pertains to it

Hyperbola

So, even a straight line, defined with calculus, is a curve.
