#m = 0#

#y = -3#

Can be re-written in slope-intercept form as

#y = 0x - 3#

Hence, the slope is 0.

We can also compute for the slope,

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

with

#y_1 = y_2 = -3#

and any arbitrary value for #x_1#, #x_2#. Just make sure to use different values for #x_1#, #x_2#. As an example, let's use

#x_1 = 1000#
#x_2 = 999#

#m = (-3 - -3)/(1000 - 999)#

#=> m = 0/1#

#=> m = 0#
