Coordinate plane
One of four parts into which the axes divide a coordinate plane.
Quadrants
A way to name a function that is defined by an equation. For an equation in x and y, the symbol f(x) replaces y and is read as "the value of f at x" or simply "f of x"

Curve
The set of all points (x,y) that are solutions to the equation.
Graph of an equation
The point in the plane that corresponds to an ordered pair (x,y).
Graph of an ordered pair
A long, thin mark that has no curves and extends in both directions without end.
Lines
A pair of numbers used to identify a point in a plane.
Ordered pair

Parallel
A number that, when substituted for the variable in an equation , results in a true statement.
Solution of an equation
Any set of ordered pairs(x,y)
Relation
