Coordinate plane graphing how to#

The coordinate system was invented in the 17th century by the French mathematician René Descartes. These perpendicular lines intersect each other at a point called the origin. Area of Triangle in Coordinate GeometryįAQs on Coordinate Plane What is a Coordinate Plane in Geometry?Ī coordinate plane is a two-dimensional plane formed by the intersection of the x-axis, the horizontal line, and the y-axis, the vertical line.The coordinates of any point are enclosed in brackets.įind out any three points that lie in the positive coordinate plane and for which the abscissa and ordinate are equal and non-negative.The fourth quadrant (+, -) is represented by the Roman numeral IV.The third quadrant (-, -) is represented by the Roman numeral III.The second quadrant (-, +) is represented by the Roman numeral II.The first quadrant (+, +) known as the positive coordinates quadrant, is represented by the Roman numeral I.Also, this is known as the positive coordinate plane as the value of both the coordinates for any point in this quadrant will be positive. Step 4: Mark the point of intersection.

Step 3: Move 6 units up, along the positive Y-axis.Move 5 units to the right, along the positive X-axis. Step 1: Draw two perpendiculars, the X-axis and Y-axis.To plot a point on the coordinate plane, follow the steps given below: Let us take the example of point P = (5, 6).

In this section, we are going to learn how to plot a point on the coordinate plane. Thus, the point on the graph has coordinates (-3, 2).

Step 4: The point is 2 units away from the origin along the positive Y-axis.

Step 3: The point is 3 units away from the origin along the negative X-axis.

Step 1: Observe the blue dot on the coordinate graph.

Observe the figure and the steps given below to locate a point on the coordinate plane.

Step 4: Find the Y-coordinate or the ordinate of the point by reading the number of units the point is above/below the origin along the Y-axis.

Step 3: Find the X-coordinate or abscissa of the point by reading the number of units the point is to the right/left of the origin along the X-axis.

Step 2: Find the quadrant by looking at the signs of its X and Y coordinates.

To locate a point on the coordinate plane, follow the steps given below: Now that we are already familiar with the coordinate plane and its parts, let us discuss how to identify points on a coordinate plane. These coordinates can be positive, zero, or negative, depending on the location of the point in the respective quadrants. A point in a coordinate plane is named by its ordered pair (x, y), written in parentheses, corresponding to the X-coordinate and the Y-coordinate. CoordinatesĬoordinates are a set of two values that locate a specific point on a coordinate plane grid, better known as a coordinate plane. Coordinate Plane GraphĪ coordinate graph sometimes referred to as a coordinate plane, consists of two number lines called axes that run perpendicular to each other. The coordinate plane definition is as follows: A coordinate plane, also known as a rectangular coordinate plane grid, is a two-dimensional plane formed by the intersection of a vertical line called the Y-axis and a horizontal line called the X-axis. It acts as a map and yields precise directions from one point to another. A coordinate plane can be used to graph points, lines, and much more. The numbers on a coordinate grid are used to locate points. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. A coordinate plane is a two-dimensional surface formed by two number lines.
