Find an ordered pair \( (x, y) \) that is a solution to the equation. \( 2 x-y=9 \) \( (x, y)=(0 . \square) \)

To solve for an ordered pair \( (x, y) \) that satisfies the equation \( 2x - y = 9 \), we can start by substituting \( x = 0 \) into the equation. When \( x = 0 \): \[ 2(0) - y = 9 \implies -y = 9 \implies y = -9. \] Thus, the ordered pair is \( (0, -9) \). Now, to double-check: substituting \( (0, -9) \) back into the original equation: \[ 2(0) - (-9) = 0 + 9 = 9. \] It holds true! So, \( (0, -9) \) is indeed a solution.
