Answer:
A
Step-by-step explanation:
Point R is (1, 5).
The transformation (<em>x</em> + 1, <em>y </em>- 1) denotes a translation of one unit to the right and one unit downwards.
Simply add one to the <em>x-</em>coordinate and subtract one to the <em>y-</em>coordinate of R. Hence:
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:
Our answer is A.
