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

3, 2, 4, 5,1

Answer 2

3 2 4 5 1

Answer 3

3 :
\[(x-(-5))^{2}+(y-(-6))^{2}=16\]

16 not 42
