Examples of plane curves


Line

Line given by the general equation:   A x + B y + C = 0

Line given by the intersept-intersept equation:   x / A + y / B = 1



Curves of the second order

Circle:   (x − a)2 + (y − b)2 = r2

Ellipse:   x2 / a2 + y2 / b2 = 1

Hyperbola:   x2 / a2 − y2 / b2 = 1

Parabola:   y2 = 2 p x
