Negin's first step to prove that the point B(7,4) lies on the circle should be: Negin should use the distance formula to calculate the length of segment AB.
By using the distance formula, she can determine whether the distance from the center of the circle A(4,4) to point B(7,4) equals the radius of the circle, which is 3. If the distances match, then point B lies on the circle.
