Coordinate Plane - Definition with Examples
What is Coordinate Plane?
A coordinate plane is a two-dimensional plane formed by the intersection of a vertical line called y-axis and a horizontal line called x-axis. These are perpendicular lines that intersect each other at zero, and this point is called the origin. The axes cut the coordinate plane into four equal sections, and each section is known as quadrant as shown below.
The given conventions are followed to locate the coordinates of a point:
- The x-coordinate or abscissa of a point is its perpendicular distance from the y-axis measured along the x-axis.
The y-coordinate or ordinate of a point is its perpendicular distance from the x-axis measured along the y-axis.
In stating the coordinates of a point in the coordinate plane, the x-coordinate comes first, and then comes the y-coordinate. We place the coordinates in brackets as (x, y).
So, in the given graph, coordinates of A are (5, 6) as it is 5 units away from the origin on positive x-axis and 6 units away from the origin on the positive y-axis.
Can you tell the coordinates of B, D, E, and F?
If a point is made somewhere on the graph as shown in the figure, how is its position represented?
To plot the ordered pair (1, 3) in the coordinate plane:
