Question

The equation of a circle is shown below.

(x + 2)2 + (y + 1)2 = 4
Niah uses the following steps to sketch a graph of the circle.

1. Obtain the center (-2, -1) and radius 2.
2. Write the equation in the form (x - (-2))2 + (y – (-1)2) = 22.
3. Draw a circle through the plot points (0, -1), (-4, -1), (-2, 1), and (-2, -3).
4. Mark the point (-2, -1) on the coordinate axis.
5. Calculate and plot the points around the center using given radius 2.

What is the correct order of steps to sketch the circle?

Answer 1

The appropriate order appears to be as follows:

(a). Write the equation in the form (x - (-2))^2 + (y-(-1))^2 = 2^2
(b). Obtain the center (-2, -1) and radius 2.
(c). Mark the point (-2, -1) on the coordinate axis.
(d). Calculate and plot the points around the center using given radius 2.
(e). Draw a circle through the plot points (0, -1), (-4, -1), (-2, 1), and (-2, -3).

Answer 2

once again thats exactly wat i guessed as well THANKS!
