In conic sections, one of
In conic sections, one of these curves is used when defining the directrix. The degenerate case of the hyperbola is two of these curves intersecting and this curve is formed by intersecting two planes. When bounded by two endpoints they are known as segments and they can be written in point slope form or slope intercept form. For 10 points, name this type of curve which on the Cartesian plane can be written with the equation y equals ax+b ["A"-"X" plus "B"].
