What is the horizontal axis in a coordinate plane?

• A. Quadrant
• B. X Axis
• C. Divide
• D. Equilateral Triangle

Answer: (B)

In a coordinate plane, the two lines that cross each other form the axes. The horizontal line is the X axis, labeled x, and it runs left to right. It captures the x-coordinate of any point, with positive values to the right and negative values to the left. The vertical line is the Y axis, labeled y, and it runs up and down, representing the y-coordinate, with positive values upward and negative values downward. Points are written as (x, y), showing how far to move horizontally first, then vertically. If a point has a y-value of zero, it lies on the horizontal axis. For example, (3, 0) sits on the X axis. Quadrants are the four regions created by the axes, not the axis itself. A divide or an equilateral triangle are unrelated to the axes in a coordinate plane.
