Which statement is NOT true about a coordinate grid?

• The vertical number line is the y-axis
• In a coordinate grid, the x-axis and the y-axis are perpendicular to each other.
• The x-coordinate is the second number in an ordered pair.
• The origin is the intersection of the x-axis and the y-axis
