The slope is # = 1/11 #

The coordinates are:
#(8 , 10) = color(blue)(x_1 , y_1)#

#( -3 , 9) = color(blue)(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 divided by change in x axis)

# = ( 9- 10) / ( -3 - 8)#

# = ( - 1) / ( -11)#

# = 1/11 #

The slope is # = 1/11 #
