Say that the Graphics object grph has a drawing area of width=200 and height=150. Fill in the blanks so that a line is drawn from the lower left corner to the upper right corner of the area.

A good answer might be:

grph.drawLine(  0, 149, 199, 0 )

Since the height is 150, and the numbering of pixels starts at zero, the Y coordinate of the lower left corner is 149.
