# Equation of a Curve

**An equation in two variables**

*X*and

*Y*with the degree of the equation being equal to or more than two is called the equation of a curve. If the graph of that equation plotted on the

*XY*Cartesian plane, it will give a shape of a curve, and not a straight line.

Example

*x ^{2}* +

*y*= 16,

^{2}*y*=

*x*. Equation of circle has been discussed ahead in this chapter.
