Question

How do you find the slope of the line `Y-3=0`?

Answer 1

The slope of `y-3=0` is `0`

Explanation:

`y-3=0` implies `y` is a constant (with a value of `3`)

as such its graph is a horizontal line (with slope 0)

`"slope" = ("change in "y)/("corresponding change in "x)`

...but for the given equation the "change in `y` is always going to be `0`
regardless of what the change in `x` is
and therefore the slope will be `0`
