Algebra 1 Practice Test

General Directions

Today you will be taking a Washington State Algebra I End-of-Course Practice Test. To complete this test, you will need to use the answer document provided with this practice test on Page 24. This practice test is designed to simulate the Washington State Algebra l testing experience.

Three different types of questions appear on this test: While taking this test, remember:

1. Read each question carefully, including diagrams and graphs.

2. For multiple-choice questions, choose the best answer from the four choices given. Mark only one response for each multiple-choice question.

3. For short-answer questions, write your answers in the box provided. You do not have to use all of the space provided. Answers may be graphs, text, or calculations.

4.If a short-answer question asks you to show your work, you must do so to receive full credit. If you are using a calculator, describe the calculation process you used in enough detail to be duplicated, including the numbers you entered and the function keys you pressed to find the answer. If a short-answer item has multiple parts, label each section of work and clearly identify your answer for each part.

A formula sheet is provided for the Algebra I End-of-Course Exam, and is provided on Page 22 and 23 of this Practice Test.

The Practice Test will be broken up into 4 different sections and completed over 3-50 minute periods:

Section 1: Questions 1-6

* Number, operations, expression and variables


* Linear equations and inequalities


* Characteristics and behaviors of linear and non-linear functions


* Data and statistics

* Be sure to answer all questions before you end each test session. However, do not spend too much time on any one question.

* If you do not know the answer to a question, make your best guess and go on to the next question.

* You will not be penalized for guessing.Algebra I End-of-Course Exam: Practice Test1. Order the following numbers from least to greatest:
