9/9 – Dilations, Scale Factor, and STRETCHING

When you multiply both the x and y coordinate by the same number, that number is called a scale factor.  The new image is called a dilation.

When you only multiply the x OR y coordinate by a number, then you are performing a vertical/horizontal stretch/shrink.  The new shape is not a dilation, as it is not similar to the original shape.

Your homework tonight was problems 6-58 and 6-59.
