Question

In the figure shown,trapezoid RSTU has vertices R(1,3),S(4,3),T(3,1),and U(2,1).

Draw the image RSTU after a dilation with a scale factor of 2,followed by a translation of 2 units down.Label the vertices EFGH

Answer 1

Answer is in the graph and below

Step by step

RSTU has vertices that dilate by 2
a) So multiply the x and y by 2
b) Then subtract -2 from y to translate down
c) label with new vertices EFGH

R(1,3), ➡️ R’ (2, 6) ➡️ E (2, 4)

S(4,3), ➡️ S’ (8, 6) ➡️ F (8, 4)

T(3,1), ➡️ T’ (6, 2) ➡️ G (6, 0)

U(2,1). ➡️U’ (4, 2) ➡️ H (4, 0)
