Answer:
7 units
Step-by-step explanation:
We are given that segment BC was translated to form segment B'C'.
We have ton find the length of B'C' after the translation
We are given that the length of segment BC is 7 units.
We know that when we translated any figure then the size , shape of figure does not change only coordinates of vertices of figures change.
When we translate segment BC then after translation we get segment B'C'
The coordinate of B change into the coordinates of B' and the coordinates of C change into the coordinates of C' .But the length of B'C' is equal to the length of segment of B'C'
Hence, the length of segment B'C' =7 units
