3. This is Jeopardy!!!:

4. Lesson 1: Writing Equations of Circles Write the equation for the following circles using the equation (x – h) 2 + (y – k) 2 = r 2. A. ʘ that passes through (4, 6) and has center (-1, 8).

5. Lesson 1: Writing Equations of Circles B. ʘ with a diameter that has endpoints (2, 0) and (-6, -6).

6. Lesson 2: Real Life App – Free Delivery? Pizza and Subs offers free delivery within 6 miles of the restaurant. The restaurant is loca- ted 4 miles west and 5 miles north of Consuela’s house. Write and graph an equation to represent this situa- tion if her house is at the origin of the coor- dinate system. Can she get free delivery?

7. 11.8(b): Do I Get It? Yes or No 1.Write the equation for a ʘ that passes through (-6, 7) and has center (-2, 4). Give the measure of the radius then graph the circle. 2.Write the equation for a ʘ that has a dia- meter with endpoints (-3, 4) and (3, 4). State the coordinates of the center and the measure of the radius. Then graph the circle.
