Which of the following is NOT a characteristic the students would have learned about coordinate planes?

• A. There are four quadrants in a coordinate plane
• B. Quadrant 2 contains only positive values
• C. Quadrant 3 has negative x-values and positive y-values
• D. Quadrants 1 and 4 have positive and negative values respectively

Answer: (B)

Understanding the properties of the four quadrants of a coordinate plane is essential for interpreting graphs and plotting points. In Quadrant 1, both x and y values are positive, which is a fundamental characteristic. In Quadrant 2, x-values are negative, while y-values are positive. This means that Quadrant 2 cannot contain only positive values—this is a misunderstanding of the quadrant's characteristics. Quadrant 3 is characterized by having both x and y values as negative, while Quadrant 4 has a positive x-value and a negative y-value. Therefore, the correct answer highlights a key point about the coordinate plane: Quadrant 2 cannot contain only positive values, making it the statement that is not accurate among the options provided.
