Graph Properties:
Distance Formula: If two points in a plane are
given by (x_{1}, y_{1}) and (x_{2}, y_{2}),
then the distance from (x_{1}, y_{1}) to (x_{2},
y_{2}) is
Definition of a Circle: A circle with radius r,
centered at (h,k) is defined as a set of points such that the distance
from any point (x, y) to the center (h,k) is equal to r.
Definition of a xintercepts: If an equation for
y is given in terms of x, the xintercepts will be all points such
that the equation give for y is equal to 0.
Definition of a yintercepts: If an equation for
y is given in terms of x, the yintercepts will be all points such
that the x value is equal to 0.
