You can put this solution on YOUR website!
Any line parallel to the given line
will have the same slope
-------------------------
slope = [ change in y ] / [ change in x ]
slope = +%28+7+-+3+%29+%2F+%28+-4+-%28-4%29+%29+
slope = +4+%2F+0+
Any number divided by +0+ is infinity,
so the slope of this line is infinite
and any line parallel to this line has
infinite slope

~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

Since x-coordinates of the two given points are the same, the straight line passing through them is VERTICAL line parallel to y-axis.


The slope is UNDEFINED for such line.

The line parallel to that line is vertical, too,

and its slope is UNDEFINED as well.
