**Plotting Ordered Number Pairs on a Coordinate Grid**

An ordered pair is a pair of numbers use to name

points on coordinate grid. The two numbers are

called the 'coordinates' of the point.

The first coordinate is the horizontal called the 'x'

coordinate.

The second is the vertical is called the 'y'

coordinate.

The point (0,0) is called the 'origin'

**Example:** Locate the point: (4,2) on graph grid

below.

**1: Locate 4 on the horozontal axes.2: Locate 2 on the vertical axes**

In the diagram above, the point (4, 2) meet at the

intersection of the two lines marked with a red dot.

The coordinates of this point are 4 and 2.

**Note:** The order pair (4,2) above does not name the

same point as the ordered pair (2,4) below.
