1.How do we write the equation of a horizontal line? What would be an example?
y = k, where k is any real number, is the equation of a horizontal line.
Ex: y = 10 is a line thru all points where y = 10
---------------------------------------------------------------
2.How do we write the equation of a vertical line? What would be an example?
x = k, where k is any real number, is the equation of a vertical line.
Ex: x = 10 is a line thru all points where x = 10.

A horizontal line says "No matter what is, always
stays the same. A way to write it is where is
a constant value.
An example would be is the number of items in a safe
which is buried deep under ground and no one knows where
it is. is the number of days that pass with the number
of items not changing.
---------------------
A vertical line says "No matter what is, is always
the same. It can be written
An example would be is all the possible temperatures
in the universe and is an instant in time
