write the equation of the line parallel to x=-16 and passes through the point (9 -10

Question

imstuck · Answer

The line x = -16 looks like this:|dw:1409520642019:dw|so in order to write the equation of the line parallel to that throught the point (9, -10), go to (9, -10) and draw the parallel line.  Like this:

The equation for that line is x = 9.  You completely discount the y coordinate because this is a vertical line.  It has no slope...well actually the slope is undefined.  But the equation is x = 9.

It could have gone through the point (9, -1) or (9, 15), or (9, 2000) and it would still have the equation x = 9.
