Question

scale factor is dilation and dilation is scale factor. we remember that scale factor is k in the equation y = kx. when you multiply an original shape by a scale factor, the new shape is ________ in size. if the scale factor is less than 1, the image will be ______ than the original. if the scale factor is greater than 1, the image will be ________ than the original.

Explanation:

When multiplying an original shape by a scale - factor, if $k > 1$, the new shape is larger as each dimension is multiplied by a number greater than 1. If $k<1$, each dimension is multiplied by a number less than 1, making the new shape smaller.

Answer:

If you multiply an original shape by a scale factor, the new shape is proportional in size. If the scale factor is less than 1, the image will be smaller than the original. If the scale factor is greater than 1, the image will be larger than the original.
