What is the slope of (-2,4) and (2,-1)?

Mar 27, 2018

$- \frac{5}{4}$

Explanation:

Use the slope fomula:

$m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

You do the second ${y}_{2}$ (which is $- 1$) minus the first ${y}_{1}$ (which is $4$), over the second ${x}_{2}$ (which is $2$) minus the first $x$ (which is $- 2$).

$\frac{- 1 - 4}{2 - \left(- 2\right)}$

Then you solve the top and bottom and are left with

$- \frac{5}{4}$
