SOLUTION: Find an equation of the line containing the centers of the two circles: x^2 + y^2- 4x + 6y + 4 = 0 and x^2 + y^2 + 6x + 4y + 9 = 0

Question 1207932: Find an equation of the line containing the centers of the two circles:

x^2 + y^2- 4x + 6y + 4 = 0 and x^2 + y^2 + 6x + 4y + 9 = 0

Put each equation into the form needed, and you can then read the center points directly from each equation.

Without explanation, the terms needed for complete-the -squares are 4 and 9.

----------and this is for the first equation, showing that center point is (2, -3).

YOU do the other equation, and use the two centers to find the line asked-for.
