[ 1 pt. ] 1. Describe how to use VALUE in the CALC menu to solve #2 from the January 2019 Algebra 1 Regents. State the answer.
[ 1 pt. ] 2. Describe how to use a graph and/or table on the TI-84 to do #4 from HW6 without Equation Solver.
[ 1 pt. ] 3. Describe a method to solve #24 from the January 2019 Algebra 2 Regents using the TI-84. State the answer.
[ 1 pt. ] 4. List the steps needed to store a 2 by 2 matrix in [A] whose first row is [4 3] and whose second row is [2 1].
[2 pts.] 5. Describe how to graph 2y > 6x + 8 on the TI-84. Name the feature of the graph that does not display on the TI-84 and how that feature can be determined without the TI-84.
[2 pts.] 6. Describe a method to solve the system {2x + 5y = 17, 3x + 2y = 9} on the TI-84. State the solution.
[2 pts.] 7. Describe, in detail, how you would use the TI-84 to teach an Algebra 1 class to graph a piecewise function & why you would teach it using that method.
