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.

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". Therefore, the center is located at point (1, -3) and is located in the fourth quadrant, last option. Hope this answers the question.

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)
