A point has the form:
Where "x" is the x-coordinate and "y" is the y-coordinate.
To plot a point you must identify the x-coordinate and the y-coordinate. You need to:
- Move "x" units to the right (if it is positive).
- Move "x" units to the left (if it is negative).
- Move "y" units up (if it is positive).
- Move "y" units down (if it is negative).
Remember that you must move "x" or "y" spaces from the origin, which is the point (0,0).
In this case, given the points:
For "a", for example, you must move 3 units to the right and and then 2 units up. Apply this procedure to each point.
Therefore, you can plot them as you can see in the picture attached:
