Students follow the example, which covers drawing a line on the graph screen from specified
endpoints using the
Draw
menu.
Draw the Slopes!
1. These are sample answers only. Segment location varies depending on the starting point
used.
a. and b. c. and d.
2. Students should notice that their segments are not necessarily the same as others depending
on the starting point used. Later, they will see that the slope and a point determine a line.
3. Students should notice that 1/2 and 2/4 have the same steepness. These segments are parallel
(or on the same line). They should also observe that segments with slopes,
M
2/3 and 3/2, are
perpendicular line segments. See graphs above.
