The slope of this equation is m=0m=0

Explanation:

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

y-3=0y3=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.
