Answer:
D(-4, -3), E(-7, 4), and F(-7, -3).
Step-by-step explanation:
The current coordinates are A(4, 2), B(7, 9), and C(7, 2).
If you reflect the coordinates over the y-axis, the y-values will not be changing, but the signs of the x-values will flip. So, you will have A'(-4, 2), B'(-7, 9), and C'(-7, 2).
When you translate the resulting triangle down 5 units, the y-values will decrease by 5 units. So, the coordinates of triangle DEF will be D(-4, -3), E(-7, 4), and F(-7, -3).
Hope this helps!
