Inverse from Determinant and Adjoint (2x2, with Formula) - Single Row or Column

Question

The determinant is -38 and the adjoint is shown. Which shows row 1 of the inverse? Fill only that row and leave the other entries blank. Use $A^{-1} = \frac{1}{\vert A \vert} 	ext{adj}(A)$.

$$\left[ {\begin{array} {cc} \fcolorbox{#1b7f3b}{#e6f7ec}{$4$} & \fcolorbox{#1b7f3b}{#e6f7ec}{$2$} \ 9 & -5 \end{array}  } ight]$$
