Answer:

B. I’(6, 3)

Step-by-step explanation:

Multiply I(4, 2) by 1½:

2 × 1½ = 3

4 × 1½ = 6

So, your new coordinate is I'(6, 3).

Answer: B. I’(6, 3)

Step-by-step explanation:

The coordinates (x,y) of a shape after dilation by a factor of k centered at the origin is given by :-

[tex](x,y)\rightarrow(kx,ky)[/tex]

Given : Rectangle HIJK has vertices H(-3, 2), I(4, 2), J(4, -3), and K(-3, -3).

The coordinates of the image of I after a dilation by a factor of 1.5 centered at the origin will be :_

[tex]I(4,2)\rightarrow I' (1.5\times4, 1.5\times2)=I'(6,3)[/tex]

Hence, the coordinates of the image of I after a dilation by a factor of 1.5 centered at the origin =I’(6, 3)
