Write down the equations of each of the circles shown below :
Problem 1 :
Problem 2 :
Problem 3 :
Problem 4 :
Problem 5 :
Problem 6 :
Problem 7 :
1) x2 + y2 = 4
2) (x – 1)2 + (y – 0)2 = 1
After expansion :
x2 + y2 – 2x = 0
3) (x – 3)2 + (y – 3)2 = 32
After expansion :
x2 + y2 – 6x – 6y + 9 = 0.
4) (x + 1)2 + (y + 1)2 = (-1)2
After expansion :
x2 + y2 + 2x + 2y + 1 = 0.
5) (x – 3)2 + (y + 1)2 = 52
After expansion :
x2 + y2 - 6x + 2y - 15 = 0.
6) (x – 0)2 + (y - 6)2 = 62
After expansion :
x2 + y2 - 12y = 0
7) (x – 4)2 + (y - 5)2 = 42
After expansion :
x2 – 8x + y2 - 10y + 25 = 0
