Question

In this question you will derive a general formula for the distance of a point from a line. Let P be the point (p,q) and L the line y=mx+b.
The slope of L is m

The slope of a line perpendicular to L is -1/m

The line through P perpendicular to L can be written as y=sx+c
where s is: -1/m
and c is: q+(p/m)
That line intersects L in the point Q=(u,v),

where u is: __________
and v is: ____________

The distance of P and Q is ________

Answer 1

what is u and v?
