Question

2x-3y+9=0 and passes through P(3,4) in general form

Answer 1

is part of the question missing? is it supposed to be parallel to the first line?

Answer 2

No sorry,Perpendicular to question

Answer 3

alrighty then! so perpendicular lines have negative reciprocal slopes
thats just a fancy way of saying -1 over the slope of one of the lines.

start by finding the slope of the first given equation by putting it in general form
2x+9=3y
(2x+9)/3=y
so now whats the slope of the original?
