A point having a negative abscissa and negative ordinate is in Quadrant III. In other words, 3.
Quadrant 1 or I = (+, +)
Quadrant 2 or II = (-, +)
Quadrant 3 or III = (-, -)
Quadrant 4 or IV = (+, -)
The abscissa is always going to be the first number (or x value) in an ordered pair.
The ordinate is always going to be the second number (or y value) in an ordered pair.
