Plotting points is an essential skill in mathematics, especially in the study of coordinate geometry. When we plot points, we are essentially marking specific locations on a graph, using the coordinates (x, y) to determine their position.

A coordinate plane is made up of two perpendicular number lines, where the horizontal line is called the x-axis and the vertical line is called the y-axis. The point where the x-axis and y-axis intersect is called the origin and is denoted by the coordinates (0, 0).

To plot a point on the coordinate plane, we locate the x-coordinate on the x-axis and the y-coordinate on the y-axis. We then draw a point at the intersection of the two coordinates.

Here are the key steps to follow when plotting points on a coordinate plane:

**Identify the x-coordinate:**This is the horizontal position of the point. It tells us how far left or right the point is from the origin.**Identify the y-coordinate:**This is the vertical position of the point. It tells us how far up or down the point is from the origin.**Locate the x-coordinate on the x-axis:**Move to the left or right on the x-axis to find the position of the x-coordinate.**Locate the y-coordinate on the y-axis:**Move up or down on the y-axis to find the position of the y-coordinate.**Plot the point:**Once you have found the intersection of the x-coordinate and y-coordinate, draw a point at that location.

Let's practice plotting some points on a coordinate plane. Here are a few points to plot:

Use the steps outlined above to plot each of these points on a coordinate plane. Remember to label each point with its corresponding letter.

By following these steps and practicing plotting points on a coordinate plane, you will become more proficient in understanding the position of points in a two-dimensional space.

Happy plotting!
