Question

Who know how did this? (need to complete the task)

Answer 1

So, you would reflect it over the y-axis first. (x,y)->(-x,y) and get A’ (1,2) B’ (2,6) C’ (4,4). Then, you rotate 90 degrees clockwise (x,y)->(y,-x). So, A”(2,-1) B” (6,-2) C” (4,-4). Hope this helps.

Answer 2

Explanation:

A(-1, 2), B(-2, 6), C(-4, 4)

You got the reflection part correct.

A'(-1, -2), B'(-2, -6), C'(-4, -4)

To rotate 90° clockwise, apply the following transformation:

A(x, y) = A(y, -x)

A"(-2, 1), B"(-6, 2), C"(-4, 4)
