Question

Triangle JKL is transformed using the rule
. Point K of the pre-image is at (4, 7).

What are the coordinates of point K" on the final image?

(–7, –4)
(–4, –7)
(4, –7)
(4, 7)

Answer 1

I don't see the transformation rule in your message — I need that to find K". Could you post the rule (for example (x,y) → (−y,−x) or (x,y) → (−x,−y), etc.)?

If helpful, here are results for common rules applied to K(4,7):
- (x,y) → (−y,−x) (reflection across y = −x) → (−7,−4)
- (x,y) → (−x,−y) (180° rotation about origin) → (−4,−7)
- (x,y) → (x,−y) (reflection across x-axis) → (4,−7)
- identity (no change) → (4,7)

So pick the one that matches your given rule.
