Linear interpolation between two known points.
I like aviation so I will give an example relative to aviation.
2000 feet of pressure altitude maximum take-off weight is 120.000 lbs
At sea level maximum take-off weight is 144.000 lbs
My current airport pressure altitude is 800 feet.
Y = ( ( X - X1 )( Y2 - Y1) / ( X2 - X1) ) + Y1
Where,
X1,Y1 = First co-ordinates,
X2,Y2 = Second co-ordinates,
X = Target X co-ordinate,
Y = Interpolated Y co-ordinate.
((2000 - 800) x (144.000 - 120.000) / (2000 - 0) + 120.000 = 134.400 lbs
