The slope is #color(blue)(5/3#

The coordinates provided are:

#(6,9) = color(blue)(x_1,y_1#

#(3,4) = color(blue)(x_2,y_2#

The formula for calculating the slope is : #color(blue)((y_2-y_1)/(x_2-x_1#

(ie; change in #y# axis divided by change in #x# axis)

#= (4-9) / (3-6)#

#= (-5) / (-3)#

#= 5/3#
