How many quadrants are formed when a plane is divided by an x and y axis?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (C)

When a plane is divided by the x-axis and the y-axis, it creates four distinct regions known as quadrants. This is because each axis divides the plane into two halves: the x-axis separates the upper half from the lower half, and the y-axis separates the left half from the right half. The four quadrants are commonly labeled as follows: 1. Quadrant I, where both x and y coordinates are positive, 2. Quadrant II, where x is negative and y is positive, 3. Quadrant III, where both coordinates are negative, and 4. Quadrant IV, where x is positive and y is negative. This division is a fundamental concept in coordinate geometry and is crucial for graphing equations and understanding spatial relationships. The formulation of these four quadrants aids in various mathematical applications, making the understanding of how axes interact essential for students in elementary math education.
