Ryan’s teacher asked him to graph circle E with equation (x – 5)2 + (y – 1)2 = 25. Below is the graph he submitted.
What, if anything, did Ryan do wrong when graphing this equation?
Answer
He graphed a circle with a radius of 5 instead of a radius of 25.
He graphed a circle with center at (-5, -1) instead of at (5, 1).
He graphed a circle with center at (-5, -1) instead of at (25, 1).
Ryan’s graph is accurate.
