Straight line equation

This function calculates the line equation to define a straight line.

A straight line is the infinite extension of the connection between two points. In order to describe the straight line, you only need the gradient to the x-axis and the point of intersection with the y-axis. The equation of a straight line is an equation that uniquely describes a straight line.

Formulas of the Straight line equation

\( f(x)= m · x + n\)

\(\displaystyle m = \frac{f - n}{x}\)

\( n = f - m · x \)

\(\displaystyle x = \frac{f - n}{m}\)
