State the formula for the distance between points (x1,y1)(x_1, y_1)(x1,y1) and (x2,y2)(x_2, y_2)(x2,y2).
A
Set x=0x=0x=0 in the circle equation and solve for yyy.
B
Forgetting that the centre coordinate is the opposite sign of the value in the bracket.
C
(x2−x1)2+(y2−y1)2
\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}
(x2−x1)2+(y2−y1)2
D
(x2−x1)2+(y2−y1)2
(x_2-x_1)^2+(y_2-y_1)^2
(x2−x1)2+(y2−y1)2
