Question

Triangle NMO is drawn with vertices N(−4, −2), M(−1, −1), O(−4 , −5). Determine the image coordinates of N′M′O′ if the preimage is translated 3 units to the left. N′(−7, −2), M′(−4, −1), O′(−7, −5) N′(−4, −5), M′(−1, −4), O′(−4, −8) N′(−4, 1), M′(−1, 2), O′(−4, −2) N′(−1, −2), M′(2, −1), O′ (−1, −5)

Answer 1

Answer: N′(−7, −2), M′(−4, −1), O′(−7, −5)

Explanation:

im right and youre wromng

Answer 2

(a) N′(−7, −2), M′(−4, −1), O′(−7, −5)

Explanation:

You want the coordinates of ∆NMO after translation 3 units left, given N(−4, −2), M(−1, −1), O(−4 , −5).

Translation

Translation by 'a' units right and 'b' units up affects the coordinates like this:

(x, y) ⇒ (x +a, y +b) . . . . . translation by (a, b)

Application

Here, the coordinates are translated 3 units left, so a=-3 and b=0. The transformation is ...

(x, y) ⇒ (x -3, y) . . . . . . . translation left 3 units

N(-4, -2) ⇒N'(-7, -2)

M(-1, -1) ⇒ M'(-4, -1)

O(-4, -5) ⇒ O'(-7, -5)

The translated coordinates match choice A.
