JKL has vertices J(10, 5), K(2, 8), and L(4, 9). It is translated right 5 units and up 4 units. What are the coordinates of J', K', and L'?

a. J'(15, 9), K'(12, 7), L'(9, 13)
b. J'(15, 9), K'(7, 12), L'(9, 13)
c. J'(14, 10), K'(7, 12), L'(10, 12)
d. J'(15, 5), K'(7, 8), L'(9, 9)

1 answer

To translate a point right 5 units and up 4 units, we add 5 to the x-coordinate and 4 to the y-coordinate. Therefore:

- J' = (10+5, 5+4) = (15, 9)
- K' = (2+5, 8+4) = (7, 12)
- L' = (4+5, 9+4) = (9, 13)

The correct answer is b. J'(15, 9), K'(7, 12), L'(9, 13).
