Question 154238: A. Find the equation of the line passing through the points (3, -5) and ( 1, -2).
B. Find the equation of the line perpendicular to the line you found above and passing throught the point ( -1, - 2)
Answer by josmiceli(19441)   (Show Source):
You can put this solution on YOUR website! (a) The formula is:
where
(3, -5) is ( , )
(1, -2) is ( , )
Actually, you could interchange (3, -5) and (1, -2) and you'd
still get the right answer
-------------------------------
Multiply both sides by 
 answer
check answer:
Does the line pass through (3, -5) and (1, -2)?
OK
OK
-------
(b)The slope of the line perpendicular to this
line must have a slope 
where 
It passes through (-1 , -2)
I can use the point-slope formula for this
Multiply both sides by 
---------------------
Does it pass through (-1, -2)?
OK
