and 
where 
would have a slope of 
.
and 
would thus be:
.
. 
and 
denote the slope of the first and second lines in this question, 
since the two lines are perpendicular to one another. Since 
, the slope of the first line would be:
.
, the point-slope equation of that line would be:
.
.
to find the 
-coordinate of the point in question:
