The slope is # = -2 #

The coordinates are:
#(3, -6) = color(green)(x_1, y_1#

#(2, -4) = color(green)(x_2, y_2#

The slope is calculated using formula :
Slope #= color(green)((y_2 - y_1)/ (x_2- x_1)# ( change in y axis / change in x axis)

# = (-4 - (-6)) / ( 2-3)#

# = (-4 + 6) / ( -1)#

# = 2 / -1#

# = -2 #
