Question

How do you find the slope of the line `y=2`?

Answer 1

The slope is `0`

The line `y=2` gives the value `y=2` for any value of `x`

So it is a horizontal line, crossing the `y-`axis at the `y-`intercept of `2`. Therefore, there is no slope, or better said: the slope is `0`

A slope-intercept equation would be `y=0*x+2`

Answer 2

The slope of a line is given by
`(Delta y)/(Delta x) =` change in `y` for a corresponding change in `x`.

For `y=2` the change in `y` (`Delta y`) is `0` regardless of the change in `x`,
so
slope of `y=2` is `0`
