Question

A segment with the endpoint X(-6,2) and Y(-1,-3) is rotated 90 degrees about the origin. What are the coordinates of X' and Y'?
1- X' (-1,-3) Y'(-6,2)
2- X' (2,6) Y' (-3,1)
3- X' (-2,-6) Y' (3,-1)
4- X' (6,-1) Y' (1,3)
Thank you for helping, and looking. Thanks

Answer 1

I believe it is #3. Don't know though?!?!

Answer 2

you can rotate the endpoints individually

Answer 3

are we rotating clockwise or counterclockwise

Answer 4

I don't know?

Answer 5

I am so confused on this question.

Answer 6

a point M(h,k) rotated clockwise 90 degrees ends up as M'( k, -h )

Answer 7

Is it #4 then?

Answer 8

clockwise
X(-6,2) - > X ' ( 2,6)
counterclockwise
X(-6,2) - > X ' ( -2,-6)

Answer 9

I am still confused a little?

Answer 10

clockwise 90 degrees
X(-6,2) - > X ' ( 2,6)
Y(-1,-3) -> Y' (-3, 1)
counterclockwise 90 degrees
X(-6,2) - > X ' ( -2,-6)
Y(-1,-3) -> Y' ( 3, -1)

Answer 11

Thank you.

Answer 12

the answer depends on whether the 90 degrees is rotated clockwise or anticlockwise

Answer 13

It didn't say in my workbook.

Answer 14

It says counterclockwise. Sorry
