Triangle wxy has coordinates w(1, 5), x(1, 1), and y(5, 1). which of the following sets of points represents a dilation of triangle wxy? a. w'(1, 9); x'(1, 1); y'(5, 1) b. w'(2, 10), x'(2, 2), y'(10, 2) c. w'(2, 6), x'(2, 2), y'(10, 2) d. w'(2, 10), x'(6, 2); y'(10, 2)

The correct answer for the question shown above is the second option, the option B, which is: B. W'(2, 10), X'(2, 2), Y'(10, 2) 
 The explanation is shown below: As you can see, the original triangle has the following coordinates  W(1, 5), X(1, 1), and Y(5, 1); the triangle must be dilated by a common scale factor, so if you analize the option B, you can notice that the triangle was dilated by a scale factor of 2.
