Ancient slingshots were made form straps of leather that cradled a rock until it was released. One would spin the slingshot in a circle, and the initial path of the released rock would be a straight line tangent to the circle at the point of release. The rock will travel the greatest distance if it is release when the angle between the normal to the path and the horizontal is -45 degrees. The center of the circular path is the origin and the radius of the circle measure 1.25 feet. Write and equation of the initial path of the rock in standard form.
