What is the equation of a circle with center (-4,7) and a radius 6
s2008m [1.1K]

Answer:

( x +4)^2 + ( y-7)^2 = 36

We can write the equation of a circle as

( x-h)^2 + ( y-k)^2 = r^2

where ( h,k) is the center and r is the radius

( x- -4)^2 + ( y-7)^2 = 6^2

( x +4)^2 + ( y-7)^2 = 36

Which ordered pair is the best estimate for the
d1i1m1o1n [39]

Answer:

-4, -6

Step-by-step explanation:

3x+6= 1x-2

2x+6= -2

2x= -8  

x= -4

Now that you have your x variable, you can go back and plug it in to your original equations:

y= 3(-4)+6,

      y= (-12)+6 therefore y= -6

y=1(-4) -2,

        y= (-4) -2 therefore y = -6
