## Sunshine447 2 years ago The equation of a circle is shown below. (x + 5)2 + (y + 6)2 = 16 Martha uses the following steps to sketch a graph of the circle. 1. Draw a circle through the plot points (-1, -6), (-9, -6), (-5, -2), and (-5, -10). 2. Obtain the center (-5, -6) and radius 4. 3. Write the equation in the form (x - (-5))2 + (y – (-6)2) = 42. 4. Mark the point (-5, -6) on the coordinate axis. 5. Calculate and plot the points around the center using given radius 4. What is the correct order of steps to sketch the circle?

Choices: 2, 1, 3, 5, 4 1, 2, 3, 4, 5 3, 2, 4, 5, 1 4, 2, 5, 1, 3

@cwrw238

3. hba

\[(x+a)^2+(y-b)^2=r^2\]

4. Sunshine447

5. hba

I agree.

6. Sunshine447

Okay, but I still don't know the steps.... :(

7. hba

(x-a)*

8. hba

@Sunshine447 Where do you think you should start ?

9. Sunshine447

either 3 or 5....?

10. Sunshine447

@hba is it 3 or 5?

11. hba

@Sunshine447 3 or 5 ?

12. Sunshine447

3 i think...

13. Sunshine447

wait....it has to be 3 cause5 isnt one of the choices.....

14. Sunshine447

so its 2? I don't understand...

15. Sunshine447

i think you'd have to write the equation right before trying to solve it....

16. Sunshine447

@hba i think its C but im positive...

17. Sunshine447

*im NOT positive....

18. Sunshine447

I think the steps in C work

19. Sunshine447

what do you mean?

20. Sunshine447

well, you cant draw a circle without something to base it on, so A is wrong

21. Sunshine447

*B is wrong

22. Sunshine447

A is wrong cause you write the equation before drawing the circle

23. Sunshine447

D is wrong for the same reason A is

24. Sunshine447

okay.....

25. Sunshine447

how do you find the center?

26. Sunshine447

yes, you can but 1 shouuld be last.. its connecting the dots

27. Sunshine447

true, but the equation should be already written... shouldn't it...?

28. Sunshine447

@nincompoop so is it a or c?

29. Sunshine447

that doesn't answer my question...... Is the answer A or C? No, I don't... Or are you implying BOTH.....

30. Sunshine447

not even close....... geometry........

31. Sunshine447

high school

32. Sunshine447

no, just geo

33. Sunshine447

so A or C... I still don't get it........

34. Sunshine447

okay thanks!

35. Sunshine447

@nincompoop i got another problem if you're willing to help....
