Prime Number
A prime number is an integer p greater than 1 with exactly two positive factors: 1 and p.
Composite Number
A composite number is an integer greater than 1 that has more than two positive factors.
Coordinate(s)
A number assigned to each point on the number line which shows its position or location on the line. In a coordinate plane the ordered pair, (x,y), assigned to each point of the plane, shows the point’s position in relation to the x-axis and y-axis.
Coordinate Plane
A plane that consists of a horizontal and vertical number line, intersecting at right angles at their origins. The number lines, called axes, divide the plane into four quadrants. The quadrants are numbered I, II, III, and IV beginning in the upper right quadrant and moving counterclockwise.
Quadrant
The four regions of a coordinate plane, each represent one-quarter of the whole coordinate plane.
In this quadrant, your coordinate point is - -
positive and positive
Quadrant I
In this quadrant, your coordinate point is - -

Quadrant II
In this quadrant, your coordinate point is -
negative and negative
Quadrant III
In this quadrant, your coordinate point is -
positive and negative
Quadrant IV

Ordered Pair
A pair of numbers that represent the coordinates of a point in the coordinate plane with the first number measured along the horizontal scale and the second along the vertical scale.
Origin
The point with coordinate 0 on a number line; the point with coordinates (0,0) in the coordinate plane.
