The equation of the circle is (x - 1)^2 + (y + 4)^2 = 3.

This is an extremely easy question.

The centre is (h,k) and the radius is r.

Do the substitution yourself.

So what?

You want people here to do your homework for you instead of you looking at your notes?

You still haven't bothered to tell us what the answer is.

Easy peezy  :  when   given  the  center  and  the  radius

Change  the  signs  on the  center  coordinates  and  square  the  radiius

(x  - 1)^2   +  (  y + 4)^2    =  9   May 29, 2021
