Answer 1

The lines of symmetry of the given circle equation are every line through the center.

Step-by-step explanation:

The equation x2 + y2 = 9 represents a circle with center at the origin (0,0) and a radius of 3 units. To find the lines of symmetry of this circle, we can draw a line connecting the origin to any point on the circumference of the circle. Any line passing through the center of the circle will divide the circle into two equal halves, making every line through the center a line of symmetry.
