Unit 2 - Lesson 12 - Grade 8: Illustrative Mathematics

A dilation with scale factor 2 sends A to B. Where is the center of the dilation?

What is the slope of this line? Does it appear in your equation?

Is (9, 11) also on the line? How do youknow?

Is (100, 193) also on the line?

Where is C mapped by the dilation with center (0, 10) and scale factor s ?

For which scale factor does the dilation with center (0, 1) send C to (9, 5, 5)? Explain how you know.

Is the point (20,13) on this line? Explain your reasoning.
