for a dilation, you can multiply each side or divide each side by the same number. it doesn't necessarily have to be 2
hint: divide each of the sides by 3

Can you help me with this one
A triangle with vertices at (1, 2), (–1, –6) and (7, –2) is translated five units to the left and 7 units upward. The coordinates of the translated triangle are:
a. (6, 9), (4, 1) and (12, 5)
b. (–4, –5), (–6, –13) and (2, –9)
c. (6, –5), (4, –13) and (12, –9)
d. (–4, 9), (–6, 1) and (2, 5) Incorrect i moved them and it got D but it was wrong ?: / @Vocaloid
start with the x-coordinates
subtract 5 from each x-coordinate first
then add 7 to each y-coordinate
okay hold on
actually your answer seems right to me, that's odd
