1. Create tables for equations: y=2x+2; y=2x-2;
y=-2x+2; y=-2x-2; substituting values

OBJECTIVE: • To use a rule to generate a table or graph on the graphing calculator [1.5.1 ] •To use a graphing calculator or graphing software to compare the tables and graphs of various rules; in particular, to decide whether a given rule defines a straight-line (linear) function by examining graphs [1.5.2] ACTIVITIES/ASSESSMENT: Create tables for equations: y=2x+2; y=2x-2; y=-2x+2; y=-2x-2; substituting values (use integers form -5 to +5 for x. NOTES: Webwork/Javascript/xytable.htm; /Webwork/Javascript/xytablepart.htm HOMEWORK: Plot and explain what causes the graphs to be different.
