What are Coordinates?
Coordinates are numerical values that represent the position of a point in a particular system, such as a Cartesian coordinate system. They are typically denoted as (x, y) for 2D points, and (x, y, z) for 3D points.
Steps to Determine the Coordinates of a Point
To determine the coordinates of a point, follow these steps:
- Step 1: Identify the location of the point in relation to the coordinate axes.
- Step 2: Assign values to the coordinates accordingly:
- Step 3: Determine the x-coordinate:
- Step 4: Determine the y-coordinate:
By following these steps, you will be able to find the coordinates of any point in a Cartesian coordinate system.
Example:
Let’s consider an example to better understand the process. Suppose we have a point P located at (3, 7).
Step 1: Since the point P is located at (3, 7), we can infer that it lies 3 units to the right and 7 units above the point of origin in the Cartesian plane.
Step 2: Assigning values to the coordinates:
x = 3
y = 7
Step 3: The x-coordinate of the point P is 3.
Step 4: The y-coordinate of the point P is 7.
Therefore, the coordinates of the point P are (3, 7).
Determining the coordinates of a point is a simple yet important mathematical concept. By accurately locating a point in a coordinate system, you can easily describe its position and use it in various mathematical calculations. Remember to follow the given steps and assign the correct values to the coordinates to determine the position of any point accurately.
