7. Write a description of what you see. How does the graph of
Y=X
compare to the graph of
Y=X
N
1
?
________________________________________________________________________________
8. Where will the line,
Y=X+2
be located? Draw in your prediction
and then use the calculator to check your work. Was your graph
correct? If not, why not?
9. Now predict and draw the following lines on the graph to your
right. Draw your own axes. Do not use the calculator.
Y=X+3
Y=X

Y=X+8
Y=X

10. Check your work! Graph each line on the calculator. Could you see all of the lines? Record
your observations.
Note
: On the TI
-
73, you need to clear a line in the Y= editor to make room for your new lines.

on your graphing calculator. Why do you think that the line is
not showing? Change your

) settings so that you are able to see these lines.
Record the changes you made.

12. Compare the lines:
Y=X
,
Y=2X
, and
Y=3X
. What do you notice? Try other lines in the form
Y = AX. Next, try to graph
Y=2X+3
without the calculator. Explain your strategy.
