Question

What is the standard form of the equation of the circle?

Answer 1

The standard form of the equation of a circle is:
$(x - a) {}^{2} + (y - b) {}^{2} = r {}^{2}$
Where the point (a,b) represents the centre and r is the radius. So, given your information, the equation will be:
${(x + 4)}^{2} + {(y + 3)}^{2} = 25$

Answer 2

(x – h)2 + (y – k)2 = r2 would be the equation
