The slope equals 0
This is a horizontal line through #y=-3#

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)#

#x_1=1#
#y_1=-3#
#x_2=8#
#y_2=-3#

#m = (-3-(-3))/(8-1)#

#m = (-3+3)/(8-1)#

#m=0/7#

The slope equals 0
This is a horizontal line through #y=-3#
