In an ordered pair, the x-coordinate comes first and the y-coordinate comes second.
Practice makes perfect
In an ( x, y) ordered pair, the first number shows the x-coordinate and the second number shows the y-coordinate. We are ready to graph H( 1 12, -1). First, we find 1 12 on the x-axis and make a mental note of this grid line. The x-coordinate 1 12 tells us to move 1 12 units in the positive horizontal direction.
Next, we find -1 on the y-axis and follow this grid line until it collides with the grid line from our x-coordinate. The y-coordinate -1 tells us to move 1 unit in the negative vertical direction.
The point H( 1 12, -1) lies on the point at which these two grid lines intersect.
