Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

tangare [24]

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =-2\\y_{1} =4\\x_{2} =6\\x_{1} =-2$

^^^Plug these numbers into the formula for slope...

$\frac{-2 - 4}{6 - (-2)}$

$\frac{-6}{8}$

^^^Can be further simplified to...

$\frac{-3}{4}$

^^^This is your slope

Hope this helped!
