• Each side length of Quadrilateral L'M'P'Q' will be 2.25 times the corresponding side length of Quadrilateral LMPQ.

• Each angle measure of Quadrilateral L'M'P'Q' will be 2.25 more than the corresponding angle measure of Quadrilateral LMPQ.

• Each side length of Quadrilateral L'M'P'Q' will be 2.25 more than the corresponding side length of Quadrilateral LMPQ.

The coordinates of the vertices of triangle XYZ are X(-2, -1), Y(6, 8) and Z(8, 4). Triangle XYZ is dilated by a scale factor of ⅚ with the origin as the center of dilation to create triangle X’Y’Z’.

If (x, y) represents the location of any point on triangle XYZ, which ordered pair represents the location of the corresponding point on triangle X’Y’Z’?​

​ ​ (a)
