for
Ax + By = C
the slope = - A/B
parallel lines have equal slopes
perpendicular lines have slopes that are opposite reciprocals of each other.
let me know what you concluded.
Decide weather the pair of lines are paralle, perpendicular, or neither.
5x+4y=3
4x+5y=1

I would have to say paralle the way I did them but I am not to good at theis type of problem.
no
according to my formula the slope
for the 1st line = -5/4
for the 2nd line = -4/5
they are neither the same, nor are they opposite reciprocals.
So the answer is neither.
perhaps you are used to changing your equation to the form y = mx + b
1st --- > y = (-5/4)x + 3/4
2nd ---> y = (-4/5)x + 1/5
now compare the m values.
.... same conclusion.
