Teresa is drawing quadrilaterals as shown below. She first drew the smaller quadrilateral and then dilated the pre-image to create the larger quadrilateral. Which algebraic representation best describes the dilation? * 7 6 5 4 2. -1 --- 0 3 4 5 6 7 8 9 10 11 12 13 14 15 1 19 O (x,y) -> (x+9,y+4) O(x,y) -> (4x, 3y) O (x,y) -> (x+3, y+3) O (x.y) -> (3x, 3y)

Answer :

The base of the small quadrilater is 3 and the base of the big cuadrilater is 9, so the correct relation is:

[tex]\frac{9}{3}=3[/tex]

so x is been multiply by 3, and the figure haven't change so the propotion in y is the same so the correct answe is:

[tex]D)(x,y)\to(3x,3y)[/tex]
