The slope $= -2$

The coordinates are:
$( - 3 , 4 ) = color(blue)(x_ 1 , y _ 1$

$( 7 , -16 ) = color(blue)(x_ 2 , y _2$

The slope is calculated using formula:
Slope $= color(blue)((y_2 - y_1) / (x_2 - x_1)$

$= ( -16 - 4 ) / ( 7 - (-3))$

$= ( -20) / ( 7 + 3 )$

$= ( -20) / 10$

$= -cancel20 / cancel10$

The slope $= -2$
