Question

PL has endpoints P(4, −6) and L(−2, 1). The segment is translated using the mapping (x, y) → (x + 5, y). What are the coordinates of P’ and L’? P’(9, -6), L’(-2, 1) P’(4, -6), L’(3, 1) P’(9, -6), L’(3, 1) P’(9, -1), L’(3, 6)

Answer 1

P is at (4, -6) and L is at (-2, 1)
The rule is (x,y) -> (x + 5, y)

For P':
(x, y) -> (x + 5, y) = (4, -6) -> (4 + 5, -6) = (9, -6)

For L'
(x, y) -> (x + 5, y) = (-2, 1) -> (-2 + 5, 1) = (3, 1)

Answer 2

Answer: C P’(9,-6), L’(3,1)
