The Main Answer is: The curve xy = c² is symmetric about the line y = -x
Given: the curve - xy = c²
To Find: Line about which the given curve is symmetric
Solution:
The given curve is an example of a Rectangular Hyperbola.
As shown in the figure, the curve is present in the 1st and 3rd quadrants due to the RHS (c²) being positive.
This means that the line of symmetricity of the curve xy = c² is in the 2nd and 3rd quadrants.
This line will be a straight line inclined equally from both the axes on their negative sides, i.e., forming an angle of 45° on both sides.
∴ Its slope (m) = tan(-45°) = -1
The equation of the line is y = mx
⇒ y = -1 × x ⇒ y = -x
Therefore, the line of symmetricity of the graph xy = c² is y = -x.
