A. 8B. 40.5C. 1417D. 4590

A.y = -6x + 1B. y = 6x – 1C. y = x + 6D.y = 6x + 1

Around the World!• There are 10 questions posted around the room. You

may start wherever you would like.• The answers are on the outside of the flap, and the

questions are on the inside. • If you complete the circuit correctly, you will have done

all 10 problems and end up back where you started!• You must show all work and answers on a piece of

notebook paper that is neatly labeled with your name and the problem numbers in the order that you did them. You will earn 1 extra credit point per problem.

Partner Challenge Race!• I will assign you a partner.• Together, you will complete the problems that I put

on the board on ONE sheet of paper with both of your names on it. (Take turns writing the work and answers for each question.)

• You will have a limited time to complete each question before I change the slide.

• At the end, we will switch papers and the partners with the most correct win!
