What is the slope of (3,1) and (-2,5)?

1 Answer

May 8, 2016

The slope $= - \frac{4}{5}$ $= -4/ 5$

Explanation:

$(3, 1) = x_{1}, y_{1}$ $(3,1) = color(blue)(x_1 , y _ 1 )$

$(- 2, 5) = x_{2}, y_{2}$ $(-2,5) = color(blue)(x_2 , y _2 )$

The slope $= \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $= color(blue)((y_2- y_1) / (x_2 - x_1)$

$= \frac{5 - 1}{- 2 - 3}$ $= (5-1) / (-2-3)$

$= \frac{4}{- 5}$ $= (4) / (-5)$

$= - \frac{4}{5}$ $= -4/ 5$
