Adjust the Zoom fields so that you see more points on the x and y axes.
Changing the Scale
Prior to proceeding with further operations, find the Zoom fields in the Chart
panel (see Figure 10.4). The Zoom fields allow you to adjust the number of
crosshatches you see on the
x
and
y
axes. In this instance, adjust the settings of
both of the fields so that you see values of
3. Figure 10.5 illustrates the fields
after you have adjusted the values. If you compare Figure 10.3 with Figure 10.5,
you can see the scale of the lines is now much finer than before. The number of
cross hatches on both axes increases.
To explore the use of the Zoom controls, adjust the scale up and down. As long as
you adjust the two controls in tandem, the appearance of the slope does not
change. Figure 10.5 illustrates the Zoom controls set with values of
3. Positive
values draw the crosshatches farther apart. Negative values draw them closer
together.
Setting Up a Contrasting Line
To make it so that you can contrast the work of one equation with that of
another, you make use of the upper and the lower equation composition areas. If
you have performed the exercises in the previous sections, you have pulled the
Cartesian plane over the lower composition area. You did this in part to be able
