    For the last question, the regression line equation formula is y=a+bx... so why did you do y=bx-a to workout the actual adult height

      the value of 'a' was negative( -136), so y=-136+1.84x or y= 1.84x-136....... i prefer the second version as its looks neater :-) but either is fine. Does that answer your question?
