Use int values, not float values, for x and y (otherwise the coordinates will not look very good when you draw them), and make sure that the x coordinate is at least 80 pixels from the right edge, and the y coordinate is at least 25 pixels from the top edge, to make sure there is room to draw the coordinates. Use a 500x500 canvas, as usual. Remember that random(a,b) can be used to get a random float value r where a≤r
