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.

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
