is a line.
recall: where and

if the slope is because there is change in '', which is equivalent to dividing by
A line to a line is a line.
There is change in '', so its slope is .
so, ...plug in the coordinates of given point (,) and slope

so, for a horizontal line to go through the point (,), we simply set or:
