Question

Find the vertices of the image after the given transformation (x,y)—> (2x, 1/3y)

Answer 1

see explanation

Explanation:

the translation rule (x, y ) → (2x,
`(1)/(3)` y )

means multiply the x- coordinate by 2 and multiply the y- coordinate by
`(1)/(3)` ), so

A (- 1, - 3 ) → A' (- 2, - 1 )

B (4, - 3 ) → B' (8, - 1 )

C (4, 3 ) → C' (8, 1 )

D (- 1, 3 ) → D' (- 2, 1 )
