Warm-Up: Review What You Know

These problems review skills you already know from earlier in the unit.

Triangle $ABC$ has vertices $A(1, 2)$ , $B(4, 2)$ , and $C(1, 5)$ .
After a translation by vector $\langle 3, -4 \rangle$ , what are the coordinates
of the image vertex $A'$ ?

$(-2, 6)$

$(4, -2)$

$(3, -4)$

$(1, -2)$
