Homework Help: Math/Vectors

Posted by Kate on Saturday, October 16, 2010 at 9:35pm.

I need help on a homework problem. "Determine a vector equation for the line perpendicular to 4x-3y=17 and through point (-2,4). The answer in the book is given as [x,y]=[-2,4]+t[-4,3].Isn't the normal to the scalar equation [4,-3] and wouldn't this be the direction vector of the line we're looking for. I thought the answer should have been =[-2,4]+t[4,-3]. Where am I making a mistake?
