Answer:
X^2 +Y^2 - 2X-4Y= 0
Step-by-step explanation:
From the circle eqn.
(x-a) ^2 +(y-b) ^2 =r^2
a=1, b= 2. r= 3
(x-1)^2 +(y-2)^2 =3^2
(x-1)(x-1)+(y-2)(y-2)=3^2
X^2 - 2x+1+y^2 -4y+4=9
X^2 +Y^2 - 2x-4y+5=9
X^2 +Y^2 - 2x-4y-4=0
The image would be (-1, 5)
7/10=70/100=70%, so the answer is seventy-percent.
