## 8th Grade Classwork – 1/26 (Due Thurs, 2/1)

Complete the mock regents in section #4 of your notebook.  Although the questions are multiple choice, you must show all necessary work.  Will be counted as a homework. Calculators allowed for all parts.  Make sure that DIAGNOSTICS and APPS – INEQUALITIES are on.

Rubric:   Check Plus –> all questions;   Check –> half the amount

How to use the calculator to find and graph residuals:

Important things to edit:

(for step #4) cross out the first part and only follow directions after you see the word OR -> (under L3, use 2nd STAT #7 instead).

(for step #5) take note that the residual graph does not use L1 and L2.  you must change L2 to L3 (or wherever you entered the residual).

## Mock Regents – Due Monday 9/25

Complete the following 24 multiple choice questions in section 4 of your notebook.  You must provide ALL work necessary to answer each question.  For questions you are unsure of, choose a math strategy you learned last year to work through the problem.  Any questions you are unsure of how to answer, leave blank. Calculators are allowed and encouraged.
