The first number in a coordinate pair tells us how far to move left or right from the origin, while the second number tells us how far to move up or down.

The X-axis is defined by the equation y = 0, representing all points where the vertical coordinate vanishes, while the Y-axis follows x = 0, showing points where the horizontal coordinate is zero. We then dive into a simple but crucial distinction between (x, y) and (y, x): the order of values matters! Through intuitive visuals and relatable examples, we clarify how reversing the coordinates leads to distinct placements, reinforcing why coordinate order is essential in graphing and geometry.

The x-coordinate of a point is the distance from origin to foot of perpendicular on X-axis. The x-coordinate is also called the abscissa. 2. The y-coordinate of a point is the distance from origin to foot of perpendicular on Y-axis. The y-coordinate is also called the ordinate. 3. The intersecting point of X-axis and Y-axis is called origin. We take origin as a reference point to locate other points in a plane. Origin is denoted by “O”. 4. The coordinates of the origin ‘O’ are (0, 0).
