WebAug 14, 2024 · Mathematical Equation for Linear Interpolation. The mathematical equation for this case is as follows: y= y 1 + (x-x 1 )⨯ (y 2 -y 1 )/ (x 2 -x 1) We need the value of y corresponding to x, which makes point B (x,y). A (x 1 ,y 1) and C (x 2 ,y 2) are the two points around B. To find the required y, type the equation above in an Excel cell.
