Question

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?

Answer 1

Choices:

2, 1, 3, 5, 4

1, 2, 3, 4, 5

3, 2, 4, 5, 1

4, 2, 5, 1, 3

Answer 2

@cwrw238

Answer 3

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

Answer 4

The radius is 4, right?

Answer 5

I agree.

Answer 6

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

Answer 7

(x-a)*

Answer 8

@Sunshine447 Where do you think you should start ?

Answer 9

either 3 or 5....?

Answer 10

@hba is it 3 or 5?

Answer 11

@Sunshine447 3 or 5 ?

Answer 12

3 i think...

Answer 13

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

Answer 14

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

Answer 15

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

Answer 16

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

Answer 17

*im NOT positive....

Answer 18

I think the steps in C work

Answer 19

what do you mean?

Answer 20

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

Answer 21

*B is wrong

Answer 22

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

Answer 23

D is wrong for the same reason A is

Answer 24

okay.....

Answer 25

how do you find the center?

Answer 26

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

Answer 27

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

Answer 28

@nincompoop so is it a or c?

Answer 29

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

Answer 30

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

Answer 31

high school

Answer 32

no, just geo

Answer 33

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

Answer 34

okay thanks!

Answer 35

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