Slope

Slope is how steep a line is.

 

Mathematical Definition

    \[Slope=\frac{\text{change\, in\,}y}{\text{change\, in\,} x}\]

or

    \[\frac{y_1-y_2}{x_1-x_2}=\frac{\Delta y}{\Delta x}\]

 

Example: The slope between the points (3,2) and (8,12)

 

    \[\frac{2-12}{3-8}=\frac{-10}{-5}=2\]
