David, Check out Bresenham's Algorithm for line drawing: (URL) It's been around forever and does not require complex math - which was not available on older computers anyways. Sometimes the old guys knew how to do stuff right. Ralph (19 years ago, 23-Mar-07, to lugnet.org.ca.rtltoronto)

(...) The points on the line take the form y = mx + b, where b is the intercept with the y-axis and m is the slope. For the problem as you describe it, b is 0 since the line crosses the y-axis at zero, and m = 1.5 or 15/10 since the slope is the (...) (19 years ago, 23-Mar-07, to lugnet.org.ca.rtltoronto)
