Answer:
changing the sign of y coordinates and then adding 4 units to them will give you translated image
Step-by-step explanation:
The translation happens in two phases. First one the reflection across x axis and the second one shifting 4 units upward
let us see them one by one.
1. Reflection along x axis.
When the triangle will be reflected along x axis, it is the y coordinates which are going to be changes
the y coordinates will now be the negative of what they were before reflection .
2. The upward shifting of the reflected image. In this process the x coordinate will again remain the same but we add 4 units to each coordinates of y in all the three vertices
