1. **State the problem:** We need to find a series of transformations that map Figure R onto Figure S. 2. **Identify coordinates:** Approximate coordinates for Figure R are $(-9,-9), (-7,-8), (-5,-7), (-6,-6)$ and for Figure S are $(-7,-4), (-4,-3), (-2,-1), (-5,-2)$. 3. **Analyze translation:** To map a point from Figure R to Figure S, calculate the vector between corresponding points. For example, from $(-9,-9)$ to $(-7,-4)$: $$\Delta x = -7 - (-9) = 2$$ $$\Delta y = -4 - (-9) = 5$$ 4. **Check if translation applies to all points:** Add $(2,5)$ to each point in Figure R: $$(-7,-8) + (2,5) = (-5,-3) \neq (-4,-3)$$ So a simple translation does not map all points exactly. 5. **Check for other transformations:** Consider a reflection or rotation combined with translation. 6. **Try reflection about the line $y = x$:** Reflect $(-9,-9)$ about $y=x$ gives $(-9,-9)$ (same point), so no change. 7. **Try rotation 90° counterclockwise about origin:** $$ (x,y) \to (-y,x) $$ For $(-9,-9)$: $$(-(-9), -9) = (9,-9)$$ which does not match Figure S points. 8. **Try rotation 90° clockwise about origin:** $$ (x,y) \to (y,-x) $$ For $(-9,-9)$: $$(-9,9)$$ no match. 9. **Try rotation 180° about origin:** $$ (x,y) \to (-x,-y) $$ For $(-9,-9)$: $$(9,9)$$ no match. 10. **Try translation after rotation:** Rotate Figure R 90° counterclockwise: Points become: $$(-9,-9) \to (9,-9)$$ $$(-7,-8) \to (8,-7)$$ $$(-5,-7) \to (7,-5)$$ $$(-6,-6) \to (6,-6)$$ Then translate by vector $(-16,2)$: $$ (9,-9) + (-16,2) = (-7,-7)$$ not matching Figure S. 11. **Try translation after reflection about $y=-x$:** Reflection about $y=-x$: $$ (x,y) \to (-y,-x) $$ For $(-9,-9)$: $$(9,9)$$ no match. 12. **Try translation after reflection about $x$-axis:** Reflection about $x$-axis: $$ (x,y) \to (x,-y) $$ For $(-9,-9)$: $$( -9, 9 )$$ no match. 13. **Try translation after reflection about $y$-axis:** Reflection about $y$-axis: $$ (x,y) \to (-x,y) $$ For $(-9,-9)$: $$(9,-9)$$ no match. 14. **Try translation after rotation 270° (or 90° clockwise) about point $(-6,-6)$:** Translate Figure R so $(-6,-6)$ is origin: $$(-9,-9) \to (-3,-3)$$ $$(-7,-8) \to (-1,-2)$$ $$(-5,-7) \to (1,-1)$$ $$(-6,-6) \to (0,0)$$ Rotate 90° clockwise: $$ (x,y) \to (y,-x) $$ $$(-3,-3) \to (-3,3)$$ $$(-1,-2) \to (-2,1)$$ $$ (1,-1) \to (-1,-1)$$ $$ (0,0) \to (0,0)$$ Translate back by adding $(-6,-6)$: $$(-3,3) + (-6,-6) = (-9,-3)$$ $$(-2,1) + (-6,-6) = (-8,-5)$$ $$(-1,-1) + (-6,-6) = (-7,-7)$$ $$ (0,0) + (-6,-6) = (-6,-6)$$ These points do not match Figure S. 15. **Conclusion:** The best fit is a translation by vector $(2,5)$ followed by a dilation (scaling) or shear, but since only translation and rotation/reflection are standard, the main transformation is a translation by vector $(2,5)$ approximately mapping Figure R onto Figure S. **Final answer:** **Translate Figure R by vector** $$\boxed{(2,5)}$$ **to map it onto Figure S.**
