Question

A figure on a coordinate plane is dilated. Point A(3, 9) is dilated to A'(1, 3)

Answer 1

Answer:

The dilation can be represented by (1/3x, 1/3y)

Bobby was correct

Explanations:

Coordinates of Point A = (3, 9)

After dilation:

Coordinates of A' = (1, 3)

Let the scale factor of dilation be represented by k

The relationship between the coordinates is:

1 = 3k or 3 = 9k

Using either of the two relationships, k = 1/3

Therefore, the dilation can be represented by (1/3x, 1/3y)
