The slope #=( - 13)/ ( 5)#

Explanation:

#(-1 , 5) = color(blue)(x_1 , y_1)#

#(4 , - 8) = color(blue)(x_2 , y_2)#

The slope is calculated using formula:

Slope #=color(blue)((y_2 - y_1)/ (x_2 - x_1)#

#=( - 8 - 5)/ ( 4 - (-1))#

#=( - 13)/ ( 4 + 1)#

#=( - 13)/ ( 5)#

The slope #=( - 13)/ ( 5)#

Explanation:

#(-1 , 5) = color(blue)(x_1 , y_1)#

#(4 , - 8) = color(blue)(x_2 , y_2)#

The slope is calculated using formula:

Slope #=color(blue)((y_2 - y_1)/ (x_2 - x_1)#

#=( - 8 - 5)/ ( 4 - (-1))#

#=( - 13)/ ( 4 + 1)#

#=( - 13)/ ( 5)#
