Answer: The new vertices are S'(-2, 4), T'(-2, 6) and U'(-4, 2).
Step-by-step explanation: Given that the triangle STU is located at S(2, 1), T(2, 3), and U(0, −1). Triangle STU is then transformed using the rule (x−4, y+3) to form the image S'T'U'.
We are to find the new co-ordinates of S', T' and U'.
To find the new co-ordinates of S', T' and U', we should subtract 4 from x co-ordinate of each vertex and should add 3 to the y co-ordinate of each vertex.
The new vertices after the transformation are as follows :
S(2, 1) ⇒ S'(2-4, 1+3) = S'(-2, 4)
T(2, 3) ⇒ T'(2-4, 3+3) = T'(-2, 6)
and
U(0, -1) ⇒ U'(0-4, -1+3) = U'(-4, 2).
Thus, the new vertices are S'(-2, 4), T'(-2, 6) and U'(-4, 2).
