To determine which ordered pair is not located in Quadrant IV, we need to recall the characteristics of the coordinate plane:
- Quadrant I: (positive, positive)
- Quadrant II: (negative, positive)
- Quadrant III: (negative, negative)
- Quadrant IV: (positive, negative)
In Quadrant IV, the x-coordinate is positive and the y-coordinate is negative.
Now, let's analyze each of the given ordered pairs:
- (1, -15): x is positive, y is negative → Located in Quadrant IV.
- (4, -2): x is positive, y is negative → Located in Quadrant IV.
- (12, -6): x is positive, y is negative → Located in Quadrant IV.
- (-11, 10): x is negative, y is positive → Located in Quadrant II.
Based on this analysis, the ordered pair that is not located in Quadrant IV is:
(−11, 10)
