let us take a peek at x = 14
hmm let us make a table :)
\(\bf \begin{array}{crllll}
x&y\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
14&-\infty\\
14&-1,000,000\\
14&-1,000\\
14&-10\\
14&-1\\
14&0\\
14&1\\
14&10\\
14&1000\\
14&1,000,000\\
14&+\infty
\end{array}\)
so... hmm notice, x = 14 is really just a vertical line, no matter what "y" is, "x" is always 14
notice the picture there, that's x = 14, the blue line
now, notice also the point -4, 2
can you think of a line that's parallel to x = 14, the blue one,
and passes through -4, 2?
