Answer:

D. A translation 1 unit to the right followed by a 270-degree counterclockwise rotation about the origin

Step-by-step explanation:

See the picture for better visual

Take segments ST and S'T'. If we extend them they will intersect at right angle.

It is the indication that the rotation is 90° or 270° but not 180°, when the corresponding segments come parallel.

The QRST is in the quadrant IV and Q'R'S'T' is in the quadrant III, which mean the rotation is 90° clockwise or 270° counterclockwise.

This rotation rule is:

(x, y) → (y, -x)

We also see the points S and T have x-coordinate of 5 but their images have y-coordinates of -6. It means the translation to the right by 1 unit was the step before rotation.

We now can conclude the correct choice is D:

A translation 1 unit to the right followed by a 270-degree counterclockwise rotation about the origin

Answer:

x = 3, y = 0

Step-by-step explanation:

2x - 2y = 6

x - y = 3

x = 3 + y

3(3 + y) + 2y = 9

9 + 3y + 2y = 9

5y = 0

y = 0

x = 3 + 0

x = 3
