Write the equation of this circle in standard form

Svetradugi [14.3K]

Answer:

Standard equation of this circle is (x +5)² + y² = 9.

Step-by-step explanation:

The equation of a circle with center at (h,k) and a radius of r is:

(x - h)² + (y - k)² = r²

Subtitute the variables with h= -5, k = 0, and r = 3

(x - (-5))² + (y - 0)² =3²

(x + 5)² + y² = 9
