Answer:
2. Kwame’s explanation and solution are incorrect. He reflected the pre-image at step 3, rather than the figure from step 2.
Step-by-step explanation:
We are given that,
The actual transformations of the co-ordinates (1,2), (1,4) and (2,3) as,
Co-ordinates x-axis y-axis 180°
(1,2) (1,-2) (-1,-2) (-1,-2)
(1,4) (1,-4) (-1,-4) (-1,-4)
(2,3) (2,-3) (-2,-3) (-2,-3)
But, in step 3, we see that,
The reflected co-ordinates from step 2 are (-1,2), (-1,4) and (-2,3).
Which is not the same as the actual co-ordinates in the 2nd column above.
Moreover, we have that,
Reflecting the original co-ordinates across the y-axis gives the result in step 3.
Hence, the best explanation for his solution is,
2. Kwame’s explanation and solution are incorrect. He reflected the pre-image at step 3, rather than the figure from step 2.
