If point (7,b ) is in Quadrant I and point ( a, -3) is in Quadrant III, in which Quadrant is the point (a,b)?

Explanation

To determine the quadrant in which the point (a, b) lies, analyze the given conditions. The point (7, b) in Quadrant I means x is positive, y (b) is positive. The point (a, -3) in Quadrant III means x (a) is negative, y is negative. For (a, b), x (a) is negative and y (b) is positive, placing it in Quadrant II. Other options are incorrect as they do not align with the sign conditions derived from the given points.
