Question

∆ABC is translated 6 units up and 3 units left to create ∆A'B'C'.
If vertex A is at (-1, 2) and vertex B is at (1, 5), then vertex A' is at
and vertex B' is at
.

Answer 1

For each coordinate point, subtract 3 from the y coordinate and add 6 to the y coordinate

\((x-3,y+6)\)

Answer 2

so for A' \((-1-3,2+6)\) and you can do the addition/subtraction

B' \((1-3,5+6)\)

and there isn't a 3rd coordinate i see
