Question

The equation of a circle is shown below.

(x – 1)2 + (y + 3)2 = 16

Which statement is true about the center of the circle?
Answer It is located on the x-axis.
It is located on the y-axis.
It is located in the third quadrant.
It is located in the fourth quadrant.

Answer 1

The equation of a circle is shown below.

(x + 7)2 + (y + 1)2 = 36

Lee uses the following steps to sketch a graph of the circle.

1. Obtain the center (-7, -1) and radius 6.
2. Write the equation in the form (x - (-7))2 + (y – (-1)2) = 62.
3. Mark the point (-7, -1) on the coordinate axis.
4. Draw a circle through the plot points (-1, -1), (-13, -1), (-7, 5), and (-7, -7).
5. Calculate and plot the points around the center using given radius 6.

What is the correct order of steps to sketch the circle?
Answer 1, 2, 3, 4, 5
3, 4, 1, 2, 5
4, 2, 5, 1, 3
2, 1, 3, 5, 4

Answer 2

Center is at (1, -3). So, It is located in the fourth quadrant.

Answer 3

Start with number 2 and there is only 1 choice where that is the first step.

Answer 4

thank you : ) : )

Answer 5

another tip is that 5 must come before 4...so it is definitely 2,1,3,5,4
