The ordered pair (6, -7) consists of two components: the x-coordinate (6) and the y-coordinate (-7).
- The x-coordinate is positive (6), which indicates that the point is to the right of the y-axis.
- The y-coordinate is negative (-7), which indicates that the point is below the x-axis.
This means that the ordered pair (6, -7) is located in the fourth quadrant (IV), where x is positive and y is negative.
So, the answer is: IV.
