A triangle has vertices at S(1, 1), T(2, −3), and U(4, 0). The triangle is translated up 3 units. What are the coordinates of the vertices of the image?

A. S'(4, 1), T'(5, −3), and U'(7, 0)
B. S'(1, 4), T'(2, 0), and U'(4, 3)

C. S'(1, 4), T'(2, −3), and U'(4, 0)
D. S'(1, −2), T'(2, −6), and U'(4, −3)

Answer:

B

Step-by-step explanation:

A translation of 3 units up, means adding 3 to the y- coordinate of the original points while the x- coordinates remain unchanged, that is

S(1, 1) → S'(1, 1 + 3) → S'(1, 4)

T(2, - 3) → T'(2, - 3 + 3) → T'(2, 0)

U(4, 0) → U'(4, 0 + 3) → U'(4, 3)
