Question

Triangle ABC has the following vertices: A (-1, 4), B (-1, 10), and C (3, 6).

It is translated to form Triangle A'B'C', and the new vertices are located at: A' (3, 4), B' (3, 10), and C' (7, 6).

Which statement below describes the translation that has occurred?

A.)4 units to the left
B.)2 units up
C.)3 units to the right
D.)4 units to the right

Answer 1

Look at the x-coordinate for each of the 3 vertices:

To get from A(-1,4) to A'(3,4) you need to go 4 to the right

To get from B(-1,10) to B'(3,10) you need to go 4 to the right

To get from C(7,8) to C'(7,6) you need to go 4 to the right

So, obviously, D must be right
