6.) Write the standard equation of the circle in the graph. http://assets.openstudy.com/updates/attachments/5104aa91e4b03186c3f99082-lyssalauren-1359260342950-mc0141.jpg my answer: (x-3)^2+(y+2)^2=9. Is that correct? 7.) A low-wattage radio station can be heard only within a certain distance from the station. On the graph below, the circular region represents that part of the city where the station can be heard, and the center of the circle represents the location of the station. Which equation represents the boundary for the region where the station can be heard?

    the center is at (3,-2) and the radius is 3 general form of a circle is (x - a)^2 + (y - b)^2 = r^2 (a,b) is the center and r = radius
