window by pressing WINDOW . Set the horizontal axis to 10 < x < 50 (beginning and ending values for intervals described previously) with Xscl = 10 (width of interval) by pressing 1 0 ENTER 5 0 ENTER 1 0 ENTER . Set the vertical axis to 0 < y < 5 (from no data points to at most five within the interval) with Yscl = 1 (counting) by pressing 0 ENTER 5 ENTER 1 ENTER .
