to be perpendicular slopes they have to be opposite reciprocals in other words, they must look like: A/B and -B/A
which one matches best to this description?
-3/4;4/3
good that's it
okay thank you could you help me some more?
I have a couple minutes, sure
thank you
the slope has to be the negative reciprocal of (-5/3) so switch the numerator/denominator and multiply by -1
I'm confused can you walk me through it please
-5 is the numerator, 3 is the denominator in the fraction (-5/3) now switch the numerator and denominator, let me know what you get.

omg I had a me moment lol so it would be -3/5
yup! now we just multiply that by -1 to get positive 3/5
now looking at your answer choices, which line has a slope of positive 3/5?
answer D
awesome, that's it
okay thanks voca
