Firstly, dilations preserve parallelism, meaning that the slope of the image is the same as that of the preimage.

  • Eliminate (1) and (2).

Now, since the center of dilation does not lie on the given line, the y-intercept of the image will be the y-intercept of the preimage multiplied by the scale factor.

  • So, the y-intercept of the image is (-4)(3/4)=-3.

Therefore, the answer is (4)
