Question

Δabc is reflected across the y-axis and then dilated by a factor of 3 using the point (−1, 2) as the center of dilation. what is the transformation of b(5, 3)? a(3, 1) b(5, 3) (2, 4)

Answer 1

The transformation of point B(5, 3) after being reflected across the y-axis and then dilated by a factor of 3 using the point (-1, 2) as the center of dilation is (-15, 6).

The transformation of point B(5, 3) can be found by first reflecting it across the y-axis, which changes its x-coordinate to -5, resulting in the point (-5, 3). Then, the point is dilated by a factor of 3 using the center of dilation (-1, 2). To dilate the point, we multiply its coordinates by 3, resulting in the point (-15, 6). Therefore, the transformation of point B(5, 3) is (-15, 6).
