Question 405072: put in standard form, state the type of graph it will produce, and center,key point, and/or radius for the following:
X^2 + (y-2)^2=7
x^2+6x+4y^2+8y=-13 ( for this one i know one must complete the square, but the 4
in front of the y throws me off on the equation into standard form)
xy=7 ( im pretty sure that this equation doesn't make a graph, but im not confident about my answer on noting)
