The height y (in centimeters) of a woman is related to the length of her radius bone x (from the wrist to the elbow) and is approximated by the linear equation y = 3.9x + 73.5 (a) Use the equation to approximate the heights of women with radius bone of lengths 20cm, 26cm, and 22cm. (b) Write the information from part (a) as three ordered pairs. (c) Graph the equation, using the data from part (b). (d) Use the graph to estimate the length of the radius bone in a woman who is 167cm tall. Then use the equation to find the length of the radius bone to the nearest centimeter.
