Answer: The single transformation that maps shape A onto shape B is a reflection across the line y = 2 Step-by-step explanation: The coordinates of the A are A(-1, 3) The coordinates of the corresponding point on B is (-1, 1) Therefore, given that the x-coordinates of the pre-image A and the image B are the same, therefore, we have that image B is a reflection of image A Also half the vertical distance between figure A and B = (3 - 1)/2 = 1 Therefore, figure A is obtained from figure B by reflection across a horizontal line, 1 unit below the lowest y-coordinate of figure A which is the line y = 3 - 1 = 2 Therefore, we have; The single transformation that maps shape A onto shape B is a reflection across the line y = 2
