1.) what is the equation of a vertical line passing through the point (2, -4)?
2.) what is the equation a horizontal line passing through the point (2, -4)?
3.) what is the two lines above relationship to each other?

The points lying on a vertical line share the same coordinate. Similarly, the points lying on a horizontal line share the same coordinate.

So, vertical lines are identified by the coordinate of their points, and have an equation like , where is a fixed real number.

Similarly, horizontal lines are identified by the coordinate of their points, and have an equation like , where is a fixed real number.

We are ready to answer the questions:

y=mx+b is the final answer!   : )

yo answer should be 6 if im not mistaken
