Write an equation of the line that is perpendicular to the line y = 1/3 x + 6 that passes through the point (2, -3).
a) y = 3x + 9
b) y = -3x - 3
c) y = -3x + 3
d) y = 1/3x + 9

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
