APPENDIX D
ACHIEVEMENT TEST (LINEAR FUNCTIONS)
The
purpose of this test is to explore your knowledge on linear equations and
related concepts, in terms of their different representations: table, graph,
algebraic and verbal. Show all your
work, in the exercises that can require it.
Use the following figure to answer items 1 and
2.
1.
The coordinates
of point C are: __________
2.
In what quadrant
is point A located? __________
Refer to the following figure to answer items 3
and 4.
3.
If point P is moved
from a quadrant to other in the Cartesian plane and its new coordinate is by
the form (x, y), in what quadrant is point P now located?

4.
If point P is now
located in the x positive axis, then, what form has the coordinate of
point P?

23. Lisa jogs 2 miles everyday. One day after running, she measures her pulse every two
minutes. These are the results. Her pulse rate was 140 beats per minute 2
minutes after running. It was 115 beats
per minute after 4 minutes. It was 105
beats per minute after 6 minutes. It
was 90 beats per minute after 8 minutes.
It was 75 beats per minute after 10 minutes. Which of these graphs best
shows her results?
