Given a triangle with vertices at points (-5, -7), (6, -4), (10, -4) and the transformed triangle via translation at (3,-7), (14,-4), ( ? ,-4) what is the missing new x coordinate?

Point A(-5,-7) turns into point A' (3,-7). The old x coordinate is added onto 8 to get the new x coordinate. Note how in the second point x = 6 --> x+8 = 6+8 = 14.

For the third point, we have x = 10 and we add 8 onto this to get x+8 = 10+8 = 18

18

side note: the y coordinate stays the same for each transformation. This means every point shifts to the right 8 units
