2. write the equation of the circle in general form

the points are

-1,-2
-1,4
2,1
-4,1

and the dot is on -1,1

(-1,-2) and (-1,4)
so these have same x values, but different y values, so these are on differnt sidef of circle

distanc between them is 6
6/2=3
radius=3

so move 3 units up from (-1,-2)
(-1,1)
so

if center is (h,k) and radius is r then
(x-h)^2+(y-k)^2=r^2

(-1,1) is center and r=3

(x-(-1))^2+(y-1)^2=3^2
(x+1)^2+(y-1)^2=9

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
