Question

Triangle ABC has vertices at A(−5, 2), B(1, 3), and C(−3, 0). Determine the coordinates of the vertices for the image if the preimage is translated 4 units right.

A′(−9, 2), B′(−3, 3), C′(−7, 0)
A′(−4, 6), B′(0, 7), C′(−5, 4)
A′(−1, 2), B′(5, 3), C′(1, 0)
A′(−5, −2), B′(1, −1), C′(−3, −4)

Answer 1

Option 3: A'(-1, 2), B'(5, 3), C'(1, 0)

Explanation:

The triangle is translated 4 units RIGHT, so we will be dealing with the x-values of the vertices of the triangle.

4 units right indicates, we are ADDING 4 to the x-values, because we are moving in the positive direction.

A(-5, 2) becomes A'(-5+4, 2) = A'(-1, 2)

B(1, 3) becomes B'(1+4, 3) = B'(5, 3)

C(-3, 0) becomes C'(-3+4, 0) = C'(1, 0)
