Slope $m=-2/3$

Given -

$x_1=7/10$
$y_1=-1$
$x_2=- 1/5$
$y_2=- 1/5$

Slope $m=(y_2-y_1)/(x_2-x_1)=(-1/5-(-1))/(-1/5-7/10)=((-1+5)/5)/((-5-7)/10)=(4/5)/((-12)/10)$
$=4/5 -:(-12)/10=4/5 xx 10/(-12)=-40/60=-2/3$

What is the slope of the line passing through the following points: (7/10,-1) , (-1/5, -1/5)(7/10,-1) , (-1/5, -1/5)?
