A parallelogram with vertices (–1, 3), (5, 1), (3, –2), and (–3, 0) is translated right 4 units, down 2 units. What are the coordinates of the vertices of the translated parallelogram? A. (3, 1), (9, –1), (7, –4), and (1, –2) B. (3, 1), (9, –1), (7, 0), and (1, –2) C. (3, 5), (9, 3), (7, 0), and (1, 2) D. (1, 7), (7, 5), (5, 2), and (–1, 4)

    Notice that you are dealing again with a translation. In this case, all original points are given. A translation to the right is adding a positive number to the x-coordinates. A translation down is subtracting a positive number from the y-coordinate.

    Here is an example. Start with point P with coordinates (2, 5). |dw:1433180266202:dw|

    Now I will translate it 5 units to the right and 4 units down. |dw:1433180354667:dw|

    The translation 5 units right, makes the x-coordinate become 2 + 5 = 7. The translation 4 units down makes the y-coordinate become 5 - 4 = 1 The translated point is P'(7, 1)

    In your problem, you need to add 4 to every x-coordinate, and subtract 2 from every y-coordinate.

    The answer is not B. You need to check every original point and every translated point of each choice to find the correct answer.

    new vertices are (x+4,y-2) where (x,y) are original coordinates.

    (–1, 3), (5, 1), (3, –2), and (–3, 0) Add 4 to each x-coordinate. What is -1 + 4 = 5 + 4 = 3 + 4 = -3 + 4 = Then subtract 2 from each y-coordinate What is 3 - 2 = 1 - 2 = -2 - 2 = 0 - 2 =
