Step-by-step explanation:

Slope = (y2 - y1) / (x2 - x1) where the 2 points are (x1, y1) and (x2, y2).

So here it is:

(8 - 3)/ (7 - (-5))

= 5/12.

2n^-3n-4=6 HURRY WITH ANSWERS PLZZZZZZZ!!!!!!!!!

diamong [38]

$2n^{-3}n-4 = 6$

$2 n^{-3}n = 10$

$\dfrac{1}{n^2} = 5$

$5n^2 = 1$

$n^2 = \dfrac{1}{5}$

$n = \pm \sqrt{ \dfrac{1}{5} }$

$n = \pm \dfrac{\sqrt{5}}{5}$
