# Deriving the Equation of a Circle

## PRELIMINARY ACTIVITY

Equations represent figures in the Cartesian plane. A “line” is represented by a linear function

**, while a “parabola” is represented by a quadratic function***y = mx + b***. This activity aims to find the equation that will represent a “Circle” in the Cartesian plane.***y = (x-h)*^{2}+ k## New Resources
