Can you use a graphing calculator to help you choose a multiple-choice answer when you work problems with properties? Yes, but you must either STORE information or use substitution into the algebraic expression. How?

The TI-nspire calculator is on the left and the TI-84 is on the right. If your school uses a different calculator, I’m sure you can find a store utility on it.

On the TI-nspire the STO button is 2 buttons above the number 7. On the TI-84 the STO button is above the ON button.
