1 Name: Hour: Unit 1 Scavenger Hunt Review Equations and Scatter Plot a) b)

2 a) b)

3 A) LT 1: I can write, solve, & check equations that represent real world situations. Write the following as an equation. Tell what each variable represents. The total cost to enter the amusement park is $5 to enter and $3 per ride. c = 59m c = total cost m = # months B) LT 3: I can combine like terms. If possible, combine like terms: 2x 2 + 6x 8x 2-12x x = 9

4 C) LT 2ab: I can solve & check equation: a) one step b) two step Solve and check. x 12 = -4 a) yes b) no D) LT 2ab: I can solve & check equation: a) one step b) two step Solve and check. p = -8 x = 11

5 E) LT 1: I can write, solve, & check equations that represent real world situations. Write the following as an equation. Tell what each variable represents. The total cost for my cell phone plan is $59 per month. 2x 2 y + 7xy F) LT 2ab: I can solve & check equation: a) one step b) two step Answer the following questions: a) Is 16 a solution to the equation? 2x + 7 = 35 b) Is -5 a solution to the equation? p = = x 5-12

6 G) LT 2ab: I can solve & check equation: a) one step Solve and check. 3x + 1 = 7 b) two step hours studied test scores H) LT 3: I can combine like terms. If possible, combine like terms 5x 2 y + 7xy 3x 2 y x 2.67

7 I) LT 2ab: I can solve & check equation: a) one step Solve and check. 4 2x = 22 b) two step c = 3r + 5 c = total cost r = # rides J) LT 2ab: I can solve & check equation: a) one step b) two step Answer the following questions: a) Is 9 a solution to the equation? 41 = 7x - 22 b) Is 9 a solution to the equation? -5 = x -45 x = 2

8 K) LT 4abc: I can display and use data in a scatter plot by using correlation and a best fit line. Give two variables that have a positive correlation. 18x 2 + 6x + 7 L) LT 2ab: I can solve & check equation: a) one step b) two step Solve and check. -4x = -44

9 M) LT 4abc: I can display and use data in a scatter plot by using correlation and a best fit line. Define: Line of Best Fit a) no b) yes N) LT 4abc: I can display and use data in a scatter plot by using correlation and a best fit line. Sketch a graph that has no correlation. x = 5

10 O) LT 2c: I can solve & check equations: c) multi step Solve and check. 3x - 4x 2 + 2x 2 + 2x 2 = 15 x = 8 P) LT 2c: I can solve & check equations: c) multi step Solve and check. 24 = 3x + 2x + 4x A line drawn on a scatter plot to show a pattern in the data and used to make predictions.

11 Q) LT 4abc: I can display and use data in a scatter plot by using correlation and a best fit line. Sketch of a scatter plot that has negative correlation.

15 Unit 1 Test (70% of your grade) 22 questions Use the backside of your LT sheet as "cheat sheet" Can use a calculator. Don't finish? Must stay after school Thursday to finish. Come prepared!!!

16 How to prepare... Complete Review Assignment (check answers) due tomorrow! Study the Learning Targets you struggled in. (see purple sheet) Write notes down on "cheat sheet" Review quizzes, classwork, practice problems.

17 Review Scavenger Hunt 1. Start at any sheet (taped to the wall). 2. Complete the problem in the correct box. 3. Hunt for the correct answer on the bottom of another sheet. 4. Complete question. 5. Repeat (2 4) until all questions have been answered. 6. Check off with Mrs. Spaeth when finished.
