To translate the triangle with vertices at (4, 3), (8, 3), and (7, 5):
-
Translate right 4 units:
- (4, 3) becomes (4 + 4, 3) = (8, 3)
- (8, 3) becomes (8 + 4, 3) = (12, 3)
- (7, 5) becomes (7 + 4, 5) = (11, 5)
-
Translate down 2 units:
- (8, 3) becomes (8, 3 - 2) = (8, 1)
- (12, 3) becomes (12, 3 - 2) = (12, 1)
- (11, 5) becomes (11, 5 - 2) = (11, 3)
Thus, the vertices of the translated triangle are (8, 1), (12, 1), and (11, 3).
So the correct answer is: (8, 1), (12, 1), and (11, 3).
