#m=-5/3#

Explanation:

determine the slope:

#(color(blue)(x_1),color(blue)(y_1)) = (1,-1)#

#(color(red)(x_2),color(red)(y_2))=(-2,-6)#

#color(green)m =(color(red)(y_2)-color(blue)(y_1))/(color(red)(x_2)-color(blue)(x_1))#

#color(green)m =(color(red)(-6)-color(blue)((-1)))/(color(red)(-2)-color(blue)(1))=-5/3#
