Question

Can someone please help me with and explain this?

Answer 1

A

Explanation:

Point R is (1, 5).

The transformation (x + 1, y - 1) denotes a translation of one unit to the right and one unit downwards.

Simply add one to the x-coordinate and subtract one to the y-coordinate of R. Hence:

`R'=((1)+1, (5) -1)=(2, 4)`

Next, we want to dilate RUST by a scale factor of three. Since the dilation is centered on the origin, we can simply multiply each coordinate by three. This yields:

`R'=(3(2), 3(4))=(6, 12)`

Our answer is A.
