Question

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

Answer 1

Slope: `0`

Explanation:

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

Slope is defined as `("change in "y)/("corresponding change in "x)`

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