perpendicular slopes are reciprocals with a change of sign
i.e. if the line in question is y = 2x
a perpendicular line would be y = -1/2x
then plug in the point (2,1) into the equation y = mx + b and you find b

you have one unknown, b.
after you have figured the slope, you have x and y
so plug in to y = mx + b. solve for b.
my slope was 3/2x
ok thats correct.
plug in (2,1)
so you should have
\[y = mx + b\] and if you plug in correctly it will become
\[1 = (3/2)*2 + b\]
solve for b.
then go back to \[y = mx + b\]
use that b to plug in and also the slope you just found for a general equation of the line.
