The calculator provided in this section can be used in
analytical geometry calculation in order to find out the linear
interpolation unknown value which lies between the two known rates.
Let the points (x_{1}, y_{1}), (x_{2}, y_{2}) and (x_{3}, y_{3}) be on the same straight line on the xy plane. This calculator can be used to find out the unknown value which lies between the two known rates.
Example :
Let the two points (0, 1) and (4, 9) be on a straight line.
We can use this calculator to find the value of k such that the point (k, 5) is on the line containing the points (0, 1) and (4, 9).
You can substitute (0, 1) and (4, 9) for (x_{1}, y_{1}) and (x_{3}, y_{3}) respectively. Leave the box of x_{2} empty and substitute 5 for y_{2}.
1. If you want to find the value of x_{2}, don't enter any value for x_{2}. 2. If you want to find the value of y_{2}, don't enter any value for y_{2}.

Linear interpolates between each pair of the given two points for set of data points can be calculated from the general formula :
