Use the following View Window parameters.
Xmin = –6.3 Ymin = –3.1
Xmax = 6.3 Ymax = 3.1
Xscale = 1 Yscale = 1

2 (X-IN)
(Calculates the x -intercept.)

3 (Y-IN)
(Calculates the y -intercept.)
• Press
e
to calculate the second set of x -/ y -intercepts. Pressing
d
returns to
the first set of intercepts.
