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)

(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
-------
(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
