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?

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

The radius is 4, right?

- hba

I agree.

- anonymous

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

- hba

(x-a)*

- hba

@Sunshine447 Where do you think you should start ?

- anonymous

either 3 or 5....?

- anonymous

@hba is it 3 or 5?

- hba

@Sunshine447 3 or 5 ?

- anonymous

3 i think...

- anonymous

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

- anonymous

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

- anonymous

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

- anonymous

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

- anonymous

*im NOT positive....

- anonymous

I think the steps in C work

- anonymous

what do you mean?

- anonymous

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

- anonymous

*B is wrong

- anonymous

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

- anonymous

D is wrong for the same reason A is

- anonymous

okay.....

- anonymous

how do you find the center?

- anonymous

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

- anonymous

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

- anonymous

@nincompoop so is it a or c?

- anonymous

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

- anonymous

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

- anonymous

high school

- anonymous

no, just geo

- anonymous

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

- anonymous

okay thanks!

- anonymous

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