YMXC (KnownYArray,KnownXArray)

where

YMXC() calculates the slope of the line.

Description

$KnownYArray$ is the Y values in the line and $KnownXArray$ is the X values in the line.
The slope of a line characterizes the direction of a line.
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
Consider two points of $Y$ Coordinates are $y_{1}$ and $y_{2}$ and $X$ Coordinates are $x_{1}$ and $x_{2}$ .
The equation used to calculate the slope from two points is:

$Slope={\frac {thechangeinY's}{thechangeinX's}}$ Or $Slope={\frac {y_{2}-y_{1}}{x_{2}-x_{1}}}$ .
