(0,-3):x*2+2y*2=18

use symmetry to find at least one more point on the graph

1 answer

To find at least one more point on the graph, we can use symmetry.

Given the equation of the ellipse: x^2 + y^2 = 18

Since the ellipse is symmetric about the x-axis and y-axis, we can find another point by considering the reflection of the point (0, -3) across the x-axis and y-axis.

1. Reflecting across the x-axis:
(0, -3) reflected across the x-axis would give us the point (0, 3).

2. Reflecting across the y-axis:
(0, -3) reflected across the y-axis would give us the point (0, 3).

Therefore, the point (0, 3) is another point on the graph of the ellipse x^2 + y^2 = 18.
