The upcoming exam on Friday, September 19 will cover the
material in appendices A and B. Some of the problems will, however, cover some
extra pre-calculus material ( mainly algebra ).
The fol lowing problems do not re present all of the
possible types of problems that could appear on the exam. Problems chosen for
the exam will be similar to homework problems, previous quizzes, examples d one
in class , and the basic problems from the workshops. You would be best prepared
by studying your class notes, previous quizzes, this practice exam, and all
homework problems. Also note that the number of problems presented in this
practice exam may not represent the actual length of the exam you see on the
exam day. It is likely that the exam will be shorter than the practice exam
here, but you should be prepared for a lengthy exam anyway.
IMPORTANT! First try these problems as if it were the real
exam ; work by yourself without the text or your
notes. This is supposed to be a gauge on what you need to work on to prepare for
the exam. Answering these problems as you might handle homework problems won’t
necessarily give you much of a clue on what you need to work on.
Instructions: Provide all steps necessary to solve the
problem. Unless otherwise stated, your answer should be exact and reasonably
simplified. Additionally, clearly indicate the value or expression that is your
final answer! Calculators are not allowed .

(b) Passes through (8,7) and is parallel to the line 5x + 4y = 3.
(c) Passes through (9,5) and is perpendicular to the line 4x – 3y = 2.
