Question

triangle XYZ has vertices X(6,-2.3), Y(7.5,5), and Z(8,4). when translated X' has coordinates (2.8,-1.3). Write a rule to describe this transformation. Then find the coordinates of Y' and Z'.

Answer 1

(x-3.2, y+1) . Y'=(4.3, 6) Z'=(4.8, 5)

The preimage (6,-2.3) differs from the image (2.8,-1.3) by subtracting the coordinates of the pre-image from the image leaving a -3.2 difference for x and a +1 for the y value. apply this rule to Y and Z to get Y' and Z'.
