To graph points on the coordinate plane, first, you will need a grid. On this grid, you have an X-axis and a Y-axis. The X-axis is the horizontal axis, and the Y-axis is the vertical axis.
1. Find the point (7,5). To do this, start at the point where the X and Y axis intersect, this point is called the origin and represents the coordinates (0,0). From here, move 7 units to the right along the X-axis, which represents the first number in the pair (7,5). Then from that point, move 5 units upwards along the Y-axis as represented by the second number in the pair.
Once you've moved 7 units to the right and 5 units up, plot a point at that location.
2. The second point to graph is (10,2). Again, starting from the origin (0,0), move 10 units to the right along the X-axis. Then, move 2 units upwards along the Y-axis.
Mark the point at this location by marking a dot on it.
Remember, the order of the numbers in the pair is important. They represent (X, Y) coordinates. Also, note that the coordinates can be negative which would mean moving left instead of right for the X-coordinate or down instead of up for the Y-coordinate.
Now, for deleting a point on your graph, simply erase or remove the dot representing the point on your plane.
