Question

1. MGSE8.G.1: Rectangle JKLM has points at (-2,2), (1,2), (1, -2), and (-2,-2), respectively. After a transformation of rectangle JKLM, rectangle ''K'L'M is formed with points (-1, 1), (2, 1), (2, -3), and (-1, -3). Describe the transformation. A. Rectangle JKLM was reflected over the origin. B. Rectangle JKLM was translated 1 unit right and 1 unit to the down. C. Rectangle JKLM was rotated 90° about point L. D. Rectangle JKLM was dilated with a scale factor of 1.

Answer 1

is addedThe points of the rectangle are

(-2, 2), (1, 2), (1, -2) and (-2, -2)

The images are

(-1, 1), (2, 1), (2, -3), (-1, -3)

By comparing the x-coordinates in all point we will find that x is add by 1

-2 becomes -1, 1 becomes 2,

means the image is (x + 1)

By comparing the y-coordinates in all points we will find that y is subtracted by 1

2 becomes 1 and -2 becomes -3

means the image is (y - 1)

That means the rule of transformation is translated 1 unit right and 1 unit down

(x + 1, y - 1)

So the right answer is B
