Introduction
This practice Algebra test includes a sample of publicly released items from NAEP.
Included with each item are the correct answer (indicated by an asterisk) and thedistracters; the percentage of Floridas responses to each of the possible answers;
and the Description, Difficulty, and Complexity of each item.
Additional publicly released items and item data may be accessed through the
NAEP Questions Tool (NQT) at
http://nces.ed.gov/nationsreportcard/itmrlsx/default.aspx . The NQT is an
interactive tool that provides access to over 2000 released questions from NAEP
assessments in all NAEP subject areas. It is also used to access NAEP assessment
items, their correct answers and distracters, and their scoring results by subject,grade, item type, difficulty, content classification, frameworks, year, and key
words.
For more information about NAEP results, go to the NAEP Data Explorer (NDE) at
http://nces.ed.gov/nationsreportcard/naepdata/ . The NDE is an interactive tool
that provides access to a wide variety of data about what students know and can
do, as well as demographic and contextual factors that may affect their
performance. The NDE produces charts, customized tables, and graphics based on
NAEP results by year and jurisdiction; significance between jurisdictions, within
variables, and across years; and gap analyses between jurisdictions or acrossyears and between groups, between years, and between groups and years.
Additional information about the knowledge and skills the mathematics
assessment is designed to measure can be found in the 2011 Mathematics
Framework, http://www.nagb.org/publications/frameworks/math-2011-
framework.pdf. The current NAEP Mathematics Framework guided the
development of all Mathematics assessments since 2005. The previous NAEP
Mathematics Framework guided the development of the mathematics assessments
between 1990 and 2003.

Question 6
The graph above shows distance versus time for a race between runnersA and B.
The race is already in progress, and the graph shows only the portion of the race
that occurred after 11 A.M.
The table on the next page lists several characteristics of the graph. Interpret
these characteristics in terms of what happened during this portion of the race.
Include times and distances to support your interpretation. (A sample
interpretation of they-intercepts is given in the table.)
