The equation of a circle is (x-3)^2+(y+8)^2=36. relative to the standard equation of a circle (x^2+y^2=r^2), how has this circle been shifted? what is the radius of the circle?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
