Answer 2

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

`y = mx + b`

Where:

m: It's the slope

b: It is the cut-off point with the y axis.

In addition, we have that by definition, a horizontal line has zero slope. Then the equation will be of the form:

`y = b`

We substitute the "y" coordinate of the given point:

`(x, y) :( 9, -7)`

So:

`-7 = b`

So, the equation is
`y = -7`

Answer:

`y = -7`
