Question

Why do you need a line attached to the circle of your solution when you graph?

A) To indicate the radius of the circle
B) To create a tangent line to the circle
C) To connect the center of the circle to a point on the circle
D) To form a chord of the circle

Answer 1

The line is attached to the circle to connect the center of the circle to a point on the circle, indicating its radius and position.

Step-by-step explanation:

The line attached to the circle of a solution when graphing is used to connect the center of the circle to a point on the circle (Option C).

When graphing a circle, the line is drawn from the center of the circle to a point on the circle to indicate the radius and position of the circle.

For example, if the equation of a circle is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius, the line helps to determine the position and size of the circle.
