Consider a circle whose equation is x+y=2x-8=0. Which statements are true? Select three options. The radius of the circle is 3 units. The center of the circle lies on the x-axis. The center of the circle lies on the y-axis. The standard form of the equation is (x-1)* * y* = 3. The radius of this circle is the same as the radius of the circle whose equation is x + y = 9,
