- Classify the following as a(n) circle, ellipse, or hyperbola:
- Give the equation of the following graphs:

Day 1

Definition (OLD): an equation in the form of or

Definition (NEW): The set of all points in a plane that are equidistant from a fixed line (directrix) and a fixed point (focus) which is not a line.

Lattice Points: points equidistant (2p) from the focus on the parabola
