Which of the following can be the value of i so that the ordered pair (i, -9) is located in Quadrant IV?
A: 8
B: 0
C: -7
D: -1
Quadrant IV is the bottom-right quadrant in a coordinate plane. In this quadrant, the x-coordinate (or the value of i) is positive, and the y-coordinate is negative.
Therefore, the value of i that would make the ordered pair (i, -9) located in Quadrant IV is A: 8.
