Question

What is the mapping notation that will transform triangle ABC to triangle A'B'C'?

A.(x + 2,y - 14)
B.(x - 4, y - 8)
C.(y, -x)
D.(-y, x)

Answer 1

The transformation is (y,-x)

Explanation:

To know the mapping notation, we need to know the coordinates of the image and the pre-image

For the pre-image, we have;

A(3,8)

B(6,8)

C(6,2)

For the image, we have

A’( 8,-3)

B’ (8,-6)

C’ (2,-6)

So let us try and get the transformation from the coordinates

We can see that this is;

(x,y) to (y,-x)
