It is (-6, -1).
270 rule represent a 270 rotation to the left which is very easy
Both will end up on the same place. Using a compass rose as an example: 270 clockwise will point to the west. 90 counterclockwise will also point west.

Point A has coordinates (x,y). Point B (Point A rotated 270°) has coordinates (y,-x). Point C (horizontal image of Point B) has coordinates (-y,-x).
It is (6, 1).
A rotation of 270 degrees counterclockwise is a transformation that turns a figure around a fixed point by 270 degrees in the counterclockwise direction. This rotation can be visualized as a quarter turn in the counterclockwise direction. It is equivalent to rotating the figure three-fourths of a full revolution counterclockwise.

You went 360o in the same direction, so you end up with a circle.
The answer depends on the centre of rotation. Since this is not given, there can be no answer.

180 degrees.
A rotation of 270 degrees counterclockwise about vertex A means that you would turn the point or shape around vertex A in a counterclockwise direction by three-quarters of a full circle. This results in a position that is equivalent to a 90-degree clockwise rotation. The new orientation will place points or vertices in a different location relative to vertex A, effectively shifting them to the left if visualized on a standard Cartesian plane.
All rotations, other than those of 180 degrees should be further qualified as being clockwise or counter-clockwise. This one is not and I am assuming that the direction of rotation is the same as measurement of polar angles. Also, a rotation is not properly defined unless the centre of rotation is specified. I am assuming that the centre of rotation is the origin. Without these two assumptions any point in the plane can be the image. With the assumptions, for which there is no valid reason, the image is (3, -4).
