Question

What is the image of R for a dilation with center (0, 0) and a scale factor of 1 1/2?

Answer 1

Option C (6, -3)

Explanation:

The given coordinates of R are (4, -2)

when R is dilated with origin and a scale factor of 3/2 then we have tell the new coordinates of R.

Now we connect this point to the origin with a line which further is dilated by length 3/2.

Therefore the new x coordinates of R will be the endpoint of the extended line =4×3/2 = 6 and new y coordinates of R will be = (-2)×3/2 = (-3)

Option C (6, -3) is the correct option.

Answer 2

The image of PQR is shown in the diagram below

The image of R is (6, -3)
