the lower equation composition area. Refer to Figure 10.7 and use the following
steps:
1. Click the Value menu item. Then in the lower equation composition area,
click to position the Value field. As in the previous exercise, this field cor-
responds to the
m
constant. This constant defines the slope of the equa-
tion. Type
2
in this field. When you type this value, type 1, a forward
slash (/), and then 2.
