To graph a point in the cartesian plane you can use rectangular coordinates. These coordinates (in a 2D plane) are given by values of x and y:
So if you want to graph a point, let's say (a,b). You must move "a" steps to the right and "b" steps upwards.
In your exercise, you have to graph the point (5,2), therefore you have to move "5" steps to right and "2" steps upwards:
