I'm totally lost on how I would even begin to answer this question, which makes me feel kind of stupid since it is the first question, haha. Help?

You can begin by looking in your textbook or notes for the definition of a dilation centered at the origin with scale factor k!

I can't believe they wouldn't have told you that formula.

Please show us what they do say when they introduce this concept.
