In a coordinate plane, what do the x and y coordinates of a point represent?

In a coordinate plane, what do the x and y coordinates of a point represent?

• A. The x-coordinate is vertical, and the y-coordinate is horizontal.
• B. The x-coordinate represents the horizontal position, and the y-coordinate represents the vertical position.
• C. The y-coordinate is always greater than the x-coordinate.
• D. X and Y represent time and distance respectively.

Answer: (B)

The x and y coordinates of a point in a coordinate plane serve specific roles related to the location of that point. The x-coordinate indicates the horizontal position of the point along the x-axis, which runs left and right. A positive x-coordinate moves the point to the right, while a negative x-coordinate moves it to the left. Conversely, the y-coordinate represents the vertical position of the point along the y-axis, which runs up and down. A positive y-coordinate moves the point upward, while a negative y-coordinate moves it downward. Thus, the correct understanding is that the x-coordinate reflects how far left or right the point is, and the y-coordinate reflects how far up or down it is, making option B the accurate choice in describing the roles of these coordinates.
