Your group will consist of yourself and four other friends or family members. call them 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 convert it to cm. This measurement will be recorded as the x coordinate.
For each student record the length of their height in feet and inches, then convert this measurement to cm. This measurement will be the subjects Y coordinate.
Write each subject measurements as ordered pair.
Plot all ordered pairs on a grid and convert it axes measurements to cm.
Select two of the ordered pairs on your grid that seem to follow an upward trend and draw in a line connecting them.
Upload the grid only as an attachment to your post.
Using two ordered pairs you selected, show us how to plug them into the slope formula to find the slope of your line.
Using one of your points and your slope plug them into the point slope formula and show us how to find the equation to your line .
Write the equation in slope intercept form.
using your equation answer question 6, Suppose a crime scene investigator uncovers a partial skeleton and identifies a bone as a human ulna ( the ulna is one of two bones in the forearm and extends from elbow to wrist) If the length of the bone is 12 in, estimate the height of the person before death.
