How do you plot points on a graph?

To plot points on a graph, you will need to first decide on the scale for the x-axis and the y-axis. This will depend on the range of values for your data. Once you have chosen the scale, you can plot the points by following these steps:

Identify the x-coordinate and y-coordinate of each point.

Starting at the origin (0,0), count along the x-axis the number of units indicated by the x-coordinate. For example, if the x-coordinate is 3, count 3 units to the right of the origin.

Next, count up or down the number of units indicated by the y-coordinate. For example, if the y-coordinate is -4, count 4 units down from the x-coordinate.

Place a dot at this point and label it with the coordinates.

Repeat this process for each additional point you want to plot.

Here is an example of how to plot points on a graph:

Suppose we want to plot the following points on a graph:

(1, 2)

(3, -1)

(-2, 4)

First, we decide on the scale for the x-axis and the y-axis. Let's say we want the x-axis to range from -3 to 4 and the y-axis to range from -5 to 5.

Next, we plot the first point, (1,2). Starting at the origin, we count 1 unit to the right along the x-axis, and then 2 units up along the y-axis. We place a dot at this point and label it with the coordinates.

Next, we plot the second point, (3,-1). Starting at the origin, we count 3 units to the right along the x-axis, and then 1 unit down along the y-axis. We place a dot at this point and label it with the coordinates.

Finally, we plot the third point, (-2,4). Starting at the origin, we count 2 units to the left along the x-axis, and then 4 units up along the y-axis. We place a dot at this point and label it with the coordinates.

Our final graph should have three points plotted on it, labeled with their respective coordinates.
