Linear interpolation between two known points

Description

In mathematics, linear interpolation is a method of curve fitting using linear polynomials. If the two known points are given by the coordinates (x_0,y_0) and (x_1,y_1), the linear interpolant is the straight line between these points. For a value x in the interval (x_0, x_1), the value y along the straight line is given from the equation. interx1), the value y along the straight line is given from an equation knowing as “Linear interpolation between two known points”
