Unit 6 Test

Instructions

Directions:
0)  Make sure you've turned in your study guide.
      On your desk - paper, pencil, calculator
      On your browser - this test, Desmos links below.
      In your backpack - phones, electronics, notes.
1)  Take the test.  If you're struggling, come back to the directions and formulae.  Give it your best shot, but keep moving through the questions.
2)  Some questions allow you to show your work.  For these, just type what steps you took to get your answer.  I may be able to give you partial credit if some of your steps are correct.  You do NOT have to show your work.
3)  Check your answers. Pay careful attention that you gave what the question was asking for.  Check formatting especially.
4)  Submit the test.  Tell me, and I will unblock GoGuardian.
5)  Close your Chromebook.  Read, draw, or work on paper schoolwork quietly.
