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?
1, 2, 3, 4, 5
3, 4, 1, 2, 5
2, 1, 4, 5, 3
4, 2, 5, 1, 3

Answer 3

It's actually common sense using context clues.

Answer 4

Tell me how you got that answer?

Answer 5

Ok, you'd have to rewrite the equation first to get the center. (2)
You then obtain the center by rewriting. (1)
Then you mark the center so that you have a visual and so that you can start graphing. (4)
Before you plot it, you need points that make up the circle. (5)
Just connect the circles to make a circle. (3)
