YMXC (KnownYArray,KnownXArray)

where

• $KnownYArray$ and $KnownXArray$ are set of values.
  • YMXC() calculates the slope of the line.

Description

YMXC (KnownYArray,KnownXArray)

• $KnownYArray$ 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 $Slope={\frac {y_{2}-y_{1}}{x_{2}-x_{1}}}$.

Examples

1. YMXC([3,4],[9,2])= -0.14285714285714285 4.285714285714286
2. YMXC([-2,7],[5,-11]) = -0.5625 0.8125
3. YMXC([4.2,14],[13,-29.3]) = -0.23167848699763594 7.211820330969267
