thats a segment AB wid perpendicular bisector

anonymous · Answer

@ganeshie8 can you find that ? :/

ganeshie8 · Answer

Yes, you need to find the line segment. NOT the perpendicular bisector ok.

ganeshie8 · Answer

look at the graph, which line segment has end points as  (-2, 2) and (4, -4) ?
can u tell ? :)

anonymous · Answer

i chose c and d but im not sure because c has -2,2 and 4,-4 but d's line passes through it @Ganeshie8

ganeshie8 · Answer

very good observation !
see that option d is longer than the segment we're looking for. It doesnt have the endpoints as (-2, 2) and (4, -4)

ganeshie8 · Answer

we want a segment wid END-POINTS as (-2, 2) and (4, -4)
not just a segment which passes thru them.

oops ! i made a mistake in interpreting the question. hang on a sec

@ganeshie8 thank you for your help!

ganeshie8 · Answer

C is definitely one answer.
lets see if d also is the answer,

ganeshie8 · Answer

linesegment in graph d :-
(-4, 4)   (7, -7)

find its midpoint,

-4+7
-----   = 3/2
  2


4 - 7
----- = -3/2
  2

ganeshie8 · Answer

which is NOT same as (1, -1) which u have worked before.

so oly C is the answer :)

ganeshie8 · Answer

see if that makes some sense
