Question

A point K with coordinates (−1, 6) is translated along the vector 〈2, 3〉 and then reflected in the y-axis. What are the coordinates of K"?
K"(1, 9)
K"(1, -9)
K"(-1, 9)
K''(-1,-9)

Answer 1

Answer:

C

Step-by-step explanation:

Under a translation < 2, 3 >

K(- 1, 6 ) → K'(- 1 + 2, 6 + 3 ) → K'(1, 9)

Under a reflection in the y- axis

a point (x, y) → (- x, y), thus

K'(1, 9 ) → K''(- 1, 9) → C
