This post is similar to the group activity on page
259 of your text. In this post you will apply multiple
skills learned throughout chapter 3 of the text. You
will use the knowledge of forming ordered pairs,
plotting ordered pairs on a rectangular coordinate
system to form a line, finding slope given two
points, and finding the equation of a line given a
point and the slope. You will apply all of this
knowledge to your measurements to find an
equation that will approximate a person’s height
given their forearm length.
• Your group will consist of yourself and four other
friends or family members (do not include
classmates) for a total of 5 subjects. Do not use
names, refer to them as subjects A, B, C, D and E
(or similar).
• For each subject, record the length of their forearm
from elbow to wrist, record this number in inches
and then show how to convert it to cm using 1 in =
2.54 cm, round to the tenths. This measurement
will represent the subject’s x coordinate.
• For each subject, record their height in feet and
inches, then show how to convert this
measurement to cm (1 ft = 12 in, then 1 in = 2.54
cm) round to the tenths. This measurement will
represent the subject’s y coordinate.
• Write each subjects’x and y coordinates as
ordered pairs, (x,y).
• Plot all ordered pairs on a plane similar to that on
page 259 but convert its axes measurements to
cm.
• Select two of the ordered pairs on your graph that
seem to follow an upward trend and draw in a line
connecting them.
Upload only the grid as an attachment to your post.
• Using the two ordered pairs you selected, show us
how to plug them into the slope formula
y2-y1
to find the slope of your line.
22-24
• Using one of the points that you chose and your
slope, plug them into the point slope formula
y – Y1 = m(x – x1) and solve for y to find the
equation of your line in slope intercept form.
• Using that equation, answer question 6 of the
group activity on page 260 Be sure to show your
calculations. Convert your answer to feet and
inches.
