Directions:
• There are four teams.• The first person from a team to raise their hand, will be
selected by the teacher. If the person answers correctly he can choose to ‘swim’ or ‘sink’.
• IF they choose to ‘swim’, they will add 2 pts to their score, or they can add 2 pts to another teams score (if they feel generous, or want an ally..)
• IF you choose to ‘sink’, you can subtract 2pts from another teams score. (muhahaha)
• The team with the most points at the end of the game WINS!!!!!!

Choose the correct statement
A circle is graphed on a coordinate plane:
A circle is a function because each input has exactly one output.
A circle is not a function because it does not pass the vertical line test.

You are hiking down hill at Red River Gorge. What is the slope of your experience (shown in
the table) X (Time) Y(Elevation)
0 minutes 8300 ft
10 minutes 7900 ft
20 minutes 7500 ft
30 minutes 7000 ft
![Page 11: Sink or Swim (Embedded Assessment 1 Review for chapter 2) Good Luck……](https://reader036.fdocuments.us/reader036/viewer/2022062404/5517fe14550346c6568b50bd/html5/thumbnails/11.jpg)
Answer
• Your elevation is decreasing 400 ft per 10 minutes. The slope therefore is -40. You are decreasing in elevation 40 ft every minute.
