Dr. Ward discovered a male femur that was 17.9 inchs in length, she concluded that the male was 65.66 inches tall. Later she discovered another male femur that was 21.6 inches long and she estimated his height to be 72.52. Let x=the length of the male femur and y=the height of the individual. Write a linear function for the height in inches, of the male in terms of the length of the femur.
Show all work.

let´s considererthe points (17.9,65.66) and (21.7,72.52)We have to find the line passinf through both points
y-72.52 = (72.52-65.66)/(21.6-17.9) *(x-21.6)
operating y = 1.8541*x + 32.4724

I've been looking at this for awhile and it doesn't make sense to me. I don't see anything in common between the two. They are close but not the same. For the first one I got y=3.668x by dividing 65.66 (height) by 17.9 (length of femur). The second one y=3.357x by doing the same (height / length of femur).
Maybe I'm missing something? (If so that means I've been out of school way too long!)
