Question

determine whether the graphs of the equations are perpendicular
8x-7y=3
8y-7x=7
the answer is yes right????

Answer 1

hmm

Answer 2

yes

Answer 3

No, they are not perpendicular


Slope of first line is 8/7 while slope of second line is 7/8


They need to be negative reciprocals of each other to be perpendicular

Answer 4

slope of the second one is..oh wait your right jim haha

Answer 5

i thought they would be though , but i forgot they have to have the negv.

Answer 6

yep it's very close, but that one negative throws it all off
