Sunshine447 Group Title

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?
