Question

Find an equation parallel to y=-5 and passing through (-2, -9)

What is the equation (answer in standard form)

Answer 1

`y=-9`

Explanation:

We want to find an equation of a line that is parallel to y=-5 and also passes through (-2,-9)

Note that y=-5 is a horizontal line.

This means that in order to be parallel to our old line, our new line must also be horizontal.

So, the equation of our new line will be whatever y-coordinate is being used from our point.

Our point is (-2,-9).

The y-coordinate is -9.

So, the equation of our horizontal line is:

`y=-9`

This is in standard form.

And we're done!
