Answer:

No solution

Step-by-step explanation:

3 x + y = 4 (1)

− 3 x − y = − 8 (2)

Add (1) and (2)

0 + 0 = -4

0 = -4 is a false statement

So, no solution

Transformation involves changing the position of a shape.

The transformation from $\triangle ABC$ to $\triangle A'B'C'$ is 90 degrees clockwise rotation

Using the coordinates of A and A', we have:

$A= (-6,3)$

$A'= (3,6)$

Notice that the x-coordinate is negated and then swapped with the y-coordinate.

i.e.

$(x,y) \to (y,-x)$

The transformation of a point from (x,y) to (y,-x) is a 90 degrees clockwise rotation.

Hence, the transformation from $\triangle ABC$ to $\triangle A'B'C'$ is 90 degrees clockwise rotation
