Let’s use Desmos to plot our points and check our equation:
Label your x-axis and y-axis
On a TABLET:
Change your scales by using two fingers on an axis
On a CHROMEBOOK:
Change your scales by typing in the axis values
-0.5 7.5 1
-2 28 5
Add your points to your graph with a data table
Graph the equation and see if it “skewers” the ordered pairs you’ve plotted
�(that means your equation is likely correct!)
How could you use your graph to find out the number of flowers in the 33rd figure?
