You have to use the trend function ..... I don’t know how well you solve the equations, but here goes
Use the trend function in excel .....
trends (Y set of values, x set of values, new x set of values, true)
now specify scale 1 and 10 in the set of values Y
for x set of values specify B and 0
and then for the new set of x values, specify the value you want to normalize
Ab
20 120
B = 120
since it works on y = mx + c
(x1, y1) = (120.0) and (x2, y2) = (0.10)
any new x you enter will be normalized based on this
so if I introduce 20 to the new x, then my answer will be 8.333 not 9 (this is wrong)
