1. Follow the steps below to help you prove or disprove that the point (1, 15) lies on the circle that is centered at the origin and contains the poin (0, 4). To earn full credit, you must show your work. Step 1: Plot a point at the origin and at (0, 4). Use these to help you draw the circle centered at the origin that contains (0, 4). Step 2: Determine the radius. Step 3: Use the radius and the coordinates of the center to write the equation of the circle. Step 4: Substitute the x- and y-coordinates of the point (1, V15) in the equation of the circle to check whether they satisfy the equation.
