Can someone give me an example please?
Perpendicular to 3x-2y=6 through (12,2)

Re: Perpendicular to....
Hi;
Put the equation into slope form by solving for y:
y = (3/2)x -3
Now you have the slope (3/2) and a point (12,2).
Now you just need a line with slope -(3/2) that intersects 3x-2y=6 and (12,2). Can you finish from here?
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Hi 3dhomejoe;
Glad to help!
How about posting what you have, this way I can check it or learn from it. Maybe you have a better method of finishing up than I do. Also others can learn to.
