#color(orange)(-1)#

Explanation:

#color(orange)(Slope)# = #(Y_2 - Y_1)/(X_2 - X_1)#

Color Code:

#color(red)Y_color(red)2#
#color(blue)Y_color(blue)1#
#color(green)X_color(green)2#
#color(yellow)X_color(yellow)1#

#(color(yellow)2, color(blue)3)# , #(color(green)-color(green)2 ,color(red)-color(red)1)#

Now plug corresponding values into the formula at the top of the explanation:

#(color(red)-color(red)1 - color(blue)3)/(color(green)-color(green)2 - color(yellow)2)#

You get:

#color(orange)(-4)/color(orange)(-4)#

Also written as:

#color(orange)1#
