The slope equals #-15/4#

Explanation:

Slope which is the change in #x# versus the change in #y#.

Slope is identified by the letter #m#

#m = (Deltay)/(Deltax)#

#m=(y_2-y_1)/(x_2-x_1)#

#(3,8)# and #(7,-7)#

#x_1=3#
#y_1=8#
#x_2=7#
#y_2=-7#

#m = ((-7)-8)/(7-3)#

#m = (-15)/(4)#

The slope equals #-15/4#
