Question 520232
Find the distance of the line PQ where P( 0, -1 ) Q ( 2, -3 )
---------
You mean the length of line PQ, or the distance from P to Q.
P(0,-1) Q (2,-3)
Don't put spaces in the points.
-------------
{{{d = sqrt(diffy^2 + diffx^2) = sqrt(2^2 + 2^2) = sqrt(8)}}}
{{{d = 2sqrt(2)}}}
d =~ 2.828
