The slope of this equation is #m=0#

Explanation:

We begin by isolating the y variable which puts the equation in slope_intercept form #y=mx+b# where
#m=# slope
and
#b=# the y-intercept.

#y-3=0#

#ycancel(-3)cancel(+3) = 0 +3#

#y=3#

This equation is is actually #y = 0x +3#

The slope of this equation is #m=0#

The graph of this line is a horizontal line through #y = 3#
A horizontal line has no rise and therefore the slope is zero.
