The formula for slope is:

#m=(y_"2"-y_"1")/(x_"2"-x_"1")#

where:
m = slope
#(x_"1", y_"1")=(0,8)#
#(x_"2", y_"2")=(2,8)#

#m=(y_"2"-y_"1")/(x_"2"-x_"1")#

#m=((8)-(8))/((2)-(0))#

#m=0/2#

#m=0#

Since the slope is 0, this means that the y values do not increase, but remain constant. Instead, only the x values decrease and increase.

Here is a graph of of the linear equation:
