Rewrite the equation y2 = \u2013 x in standard form as x2 + y2 = 36. STEP 2. Identify the center and radius. From the equation, the graph is a circle centered at the origin with radius. r = 36 = 6.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
