The slope $= -1/2$

The coordinates are:
$(-3,-6) = color(blue)(x_1,y_1$

$(3,-9) = color(blue)(x_2,y_2$

The slope is calculated using formula:
Slope $= (y_2- y_1) / (x_2- x _1)$

$= (-9 - (-6)) / (3 - (-3))$

$= (-9 + 6) / (3 + 3$

$= (-3) / (6)$

$= -1/2$

What is the slope of the line passing through the following points: (-3,-6); (3,-9) (-3,-6); (3,-9)?
