Ordered Pair - Locating a Point

D. Russell
The **x-coordinate** is always the first number in the pair and the **y-coordinate** is always the second number in the pair. The point below shows the following ordered pair:(4, -2). The point is represented by a black dot. Therefore (x,y) = (4, -2). To identify the ordered pairs or to locate points, you start at the origin and count the units along each axis. This point show 4 to the right, and 2 down.
