#m=17#

Explanation:

We'll use the slope formula: #m=(y_2-y_1)/(x_2-x_1)#

If we let
#(20,-3)->(color(red)(x_1),color(blue)(y_1)) # and #(19,-20)->(color(red)(x_2),color(blue)(y_2))# then,

#m=color(blue)(-20-(-3))/color(red)(19-20)=color(blue)(-20+3)/color(red)(-1)=(-17)/-1=17#

So the slope #(m)# is #17#
