The equation does not have and y variable in it: it is of the form x = c. Alternatively, the x coordinates of both points are the same and the y coordinates are not.
If you have an equation that looks like y=mx+b then the m is the slope. If you have two points then you use the formula Y2-Y1/X2-X1
By substitution
The orientation of "z" can depend on the context. In mathematics and physics, "z" often represents a vertical axis in a three-dimensional Cartesian coordinate system, where "x" and "y" are typically horizontal axes. However, in other contexts, such as graphing or on a page, "z" could be represented in a horizontal manner. Therefore, without additional context, it's difficult to definitively classify "z" as vertical or horizontal.
A tetrahedron has six edges, and each edge can be considered a vertical line segment when viewed from different orientations. However, if you are referring to vertical lines in a geometric sense, typically there are no true vertical lines in a tetrahedron, as it is a three-dimensional shape without a defined vertical orientation. Thus, depending on the interpretation, the answer could be either six (if considering edges as vertical lines) or none (if strictly adhering to the concept of verticality).

Not greatly. To graph an inequality, you start off graphing the corresponding equality. It is only then that you select one side or the other (with or without the graph itself), as the region of interest.

You cannot. As soon as you have a line segment you have a line.
you cannot graph it without an equal sign and an x value.
Only basic calculators without graphing capabilities are allowed on the GRE exam.
To create shapes. Think about it, without vertical lines there would never be tv....
yes
