Question

Medal+fan for anyone who can give an answer+explanation.The equation of line XY is (y−3) = negative 2 over 3(x − 4). What is the slope of a line perpendicular to XY?

−2

3

negative 2 over 3

3 over 2

Answer 1

put it into the proper equation of a line y=mx+b, where m is your slope.


A line perpendicular to that one, would have an inverse and opposite slope, so for example if
you end up 2 as your m in y=mx+b, it would be a -1/2 slope

Answer 2

That doesnt exactly open any options with this question. I put this up because I did that already but got stuck

Answer 3

i think it ends up with the line y=3x-12, perpendicular slope would be -1/3

Answer 4

I see where you went with it but I dont understand how it can match the answer optins if you put it like that

Answer 5

It got be -3/2

Answer 6

How did you get that?

Answer 7

its 3/2 not negative

Answer 8

I MET -2/3 because when you FOIL

Answer 9

teja, can you explain your answer?

Answer 10

yes
