Question

What is the equation of this circle?

(x – 1)2 + y2 = 2

(x + 1)2 + y2 = 4

(x + 1)2 + y2 = 2

(x – 1)2 + y2 = 4

Answer 1

can you point out or identify the center?

Answer 2

Yes, 1?

Answer 3

1 comma what

Answer 4

1,0

Answer 5

1 is the x coordinate

Answer 6

better

Answer 7

so how many units away is that center point from any other point on the circle

Answer 8

So the radius is 2 so the answer is (x – 1)2 + y2 = 4?

Answer 9

good you nailed it
