Question

I need to know the answer!!

Answer 1

Next time, please begin with a question of your own, and share whatever work you have done.

Look at the illustration.  You want to reflect point J in the origin.  Point J's coordinates are (0,3).  If you reflect this point in the origin, you'll get the new point J' as (0,-3).

Next, reflect point I in the origin.  The original point I is (-4,4).  Reflecting this in the origin takes you from Quadrant 2 to Quadrant 4.  The coordinates of the new point I' are (4,-4).  Spend enuf time with this so that it becomes clear.

Next, reflect point K in the origin.  You might want to draw a straight line thru point K and the origin.  The new point, K', will lie on this line the same distance from the origin  as is the old point K is from the origin.
