Linear interpolation - Wikipedia
https://en.wikipedia.org/wiki/Linear_interpolationIf the two known points are given by the coordinates and , the linear interpolant is the straight line between these points. For a value x in the interval , the value y along the straight line is given from the equation of slopes which can be derived geometrically from the figure on the right. It is a special case of polynomial interpolation with n = 1.

en.wikipedia.org › wiki › Linear_interpolationGiven the two red points, the blue line is the linear interpolant between the points, and the value y at x may be found by linear interpolation. In mathematics, linear interpolation is a method of curve fitting using linear polynomials to construct new data points within the range of a discrete set of known data points.
Interpolation - Wikipedia
https://en.wikipedia.org/wiki/InterpolationThis table gives some values of an unknown function . Interpolation provides a means of estimating the function at intermediate points, such as . We describe some methods of interpolation, differing in such properties as: accuracy, cost, number of data points needed, and smoothness of the resulting
