To check the symmetry, let's analyze the equation \( 6 x^{2}-9 y^{2}=7 \): 1. **Symmetry with respect to the \( x \)-axis**: Replace \( y \) with \( -y \): \[ 6x^2 - 9(-y)^2 = 7 \Rightarrow 6x^2 - 9y^2 = 7 \] This remains the same, so the graph is symmetric about the \( x \)-axis. 2. **Symmetry with respect to the \( y \)-axis**: Replace \( x \) with \( -x \): \[ 6(-x)^2 - 9y^2 = 7 \Rightarrow 6x^2 - 9y^2 = 7 \] This also remains the same, indicating symmetry about the \( y \)-axis. 3. **Symmetry with respect to the origin**: Replace both \( x \) with \( -x \) and \( y \) with \( -y \): \[ 6(-x)^2 - 9(-y)^2 = 7 \Rightarrow 6x^2 - 9y^2 = 7 \] This still holds, confirming symmetry about the origin. Hence, the answer is: \( \checked \) A. origin \( \checked \) B. \( y \)-axis \( \checked \) C. \( x \)-axis
