In an ordered pair, the x-coordinate comes first and the y-coordinate comes second.
Location: Quadrant IV
Graph:
In an (x,y) ordered pair, the first number shows the x-coordinate and the second number shows the y-coordinate.
To graph (2,-1), we first find 2 on the x-axis and make a mental note of this grid line. The x-coordinate 2
tells us to move two 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 one unit in the negative vertical direction.
The point F(2,-1) lies on the point at which these two grid lines intersect. We can see that the point is in Quadrant IV.
