Question

How do you find the slope of the line passing through y=8?

Answer 1

Slope: `color(green)(0)`

Explanation:

Slope is by definition the change in `y` divided by a corresponding change in `x`,
but if `y=8` the value of `y` does not change (i.e. the "change" is always `0)`
and therefore the slope is always `0` when `y=8`
