Acircle that is centered at the origin contains the point (0,4). how can you prove or disprove that the point (2,
6
) also lies on the circle? does the point (2,
6
) lie on the circle?
a) substitute the radius and the point (0,4) into x2 + y2 = r2 and simplify. the point (2,
6
) lies on the circle.
b) substitute the points (0,4) and (2,
6
) into the distance formula. the point (2,
6
) lies on the circle.
c) substitute the radius and the point (2,
6
) into x2 + y2 = 1 and simplify. the point (2,
6
) does not lie on the circle.
d) substitute the radius and the point (2,
6
) into x2 + y2 = r2 and simplify. the point (2,
6
) does not lie on the circle.
