Answer:

see explanation

Step-by-step explanation:

the translation rule (x, y ) → (2x, \frac{1}{3} y )

means multiply the x- coordinate by 2 and multiply the y- coordinate by \frac{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 )

Answer:

1. X axis, 8, 3

2. Y axis, 4,-9

Step-by-step explanation:

The rule of reflections that the place opposite of the axis is negative so:

The rule for x-axis reflection is (x,-y)

The rule for y-axis is (-x,y)

For the first one, x has remained the same, so that means it’s a x-axis reflection.

So change -3 to 3

Same for the next one.

-9 is not changed so that means it’s a y-axis reflection.

And the point is 4,-9
