Hello!! If you may please help me understand this question. I don’t understand at all what to do. If you may be detailed so I can understand the process. Thank you!!
There are four problems
1. Write the equation of a circle whose center is (-2, 0) and has the point (-5,-6)
on its circumference.
2.Write the equation of a circle whose center is (-3, -1) and has the point (-4,-5)
on its circumference.
3.What are the coordinates of the center and the length of the radius of the circle
whose equation is
(x+ 1)^2 + (y - 5)^2 = 16?
4. A circle is represented by the equation x^2 + (y - 3)^2 = 13. What are the
coordinates of the center of the circle and the length of the radius?
