Ryan’s teacher asked him to graph circle E with equation (x – 5)2 + y2 = 25. Below is the graph he submitted.What, if anything, did Ryan do wrong when graphing this equation?
He graphed a circle with a radius of 25 instead of a radius of 5.
He graphed a circle with center at (5, 0) instead of at (-5, 0).
He graphed a circle with center at (5, 0) instead of at (25, 0).
Ryan’s graph is accurate.
