Triangle KID has vertices at K(-5,2), I (-10,2) , D (-5,6).Triangle KID is dilated to form a new triangle with vertices at (-5/3, 2/3), (-10/3, 2/3), (-5/3, 2). Which represents the dilation that transforms KID to K'I'D'?

• (x,y)----- > (5/2x, 5/2y)

• (x,y)----- > (2/3x, 2/3y)

• (x,y)----- > (3x, 3y)

• (x,y)----- > (1/3x, 1/3y)

Triangle WHY was dilated to form W'H'Y' with the rule (x, y) --------> (1.2x, 1.2y). Which statement is true?

• W'H'Y' is smaller than WHY because the scale factor is less than one.

• W'H'Y' is larger than WHY because the scale factor is less than one.

• W'H'Y' is larger than WHY because the scale factor is greater than one.

• W'H'Y' is smaller than WHY because the scale factor is greater than one.
