the vertical number line on a coordinate plane

x- axis

the horizontal number line on a coordinate plane

ordered pair

A pair of numbers used to locate a point on a coordinate plane (x,y)

quadrant

one of four sections into which the coordinate plane is divided

origin

(0,0) Intersection of the x and y axes. Center of the coordinate plane.

Quadrant I

(+,+)

Quadrant II

(-,+)

Quadrant III

(-,-)

Quadrant IV

x-coordinate

The first number of an ordered pair. It corresponds to a number on the x-axis.

y-coordinate

The second number of an ordered pair. It corresponds to a number on the y-axis.
