If you are just adding those two decimals together, the answer would be 100.871.
83.971
+ 10.900 (make believe there are two zeros)

100.871
Hmm...I tried to divide 29 by 14, and I got 2.07142857143.... Does it let you round the decimal..?
Point-slope form is y - y1 = m(x - x1). We just need to plug in our stuff. This gives us y - 9 = 4(x - 3). I am not sure if you need to simplify, but if you do, y - 9 = 4x - 12.
Y = kx where k is a constant
27 = k*9
k = 27/9 = 3
required variation is y = 3x
