Slope: $0$ $0$

$3 y - 9 = 0$ $3y-9=0$ (equivalent to $y = 3$ $y=3$ ) is the equation of a horizontal line.

Slope is defined as $\frac{change in y}{corresponding change in x}$ $("change in "y)/("corresponding change in "x)$

but no matter what change we make to $x$ $x$ the value of $y$ $y$ states equal to $3$ $3$ ;
so the change in $y$ $y$ is always $0$ $0$

How do you find slope given 3y-9=03y−9=03y-9=0?
