Start (when you are ready to match the graph)
1.) Sketch a graph of the graph that you were trying to match
a.)What variable is being represented on the y-axis ?
(label this) ____________
units ?_________
b.)What variable is being represented on the x-axis ?
(label this) ____________ units ?___________
c.) What does the y-intercept represent ?
_____________________________________
Try a second time to match the graph that you
sketched by hitting the “retry” key on the
calculator.
2.) Hit the “new” button on the graphing calculator to generate a different graph and
then sketch the graph below
Hit the “retry” button to perfect your
matching of the graph.
Discuss the different properties of your
graph below :
