Students use an input/output table to graph the given equation. Once graphed, they determine if the equation is linear or nonlinear.
DESIGNED WITH THE END IN MIND! We revisit this page on a few occasions.
**Most of the equations are linear (because the unit is focused on linear equations), so we look for different ways to identify linear equations by their format rather than always having to graph them: no exponents, may or may not have a coefficient for x, may or may not have a constant, can divide x but not divide by x, etc.
**After we have covered identifying slope and y-intercept, I have my students revisit this page, find the slope and y-intercept of each linear graph, and identify how this information is represented in each equation (they love this - a total AHA! moment).
I use this as my first activity to introduce linear equations. Students should already be familiar with using tables to graph equation, making this an easy introduction to the new unit. I have them glue their sheet into an interactive notebook but it could just as easily be hole-punched and placed in a binder.
