First step is to find the slope intercept form of the line
[tex]\begin{gathered} 2x-3y=9 \\ -3y=-2x+9 \\ y=-\frac{2}{-3}x+\frac{9}{-3} \\ y=\frac{2}{3}x-3 \end{gathered}[/tex]A parallel line to the given line is the one that has an equation with the same slope, it means 2/3. In this case, all options are correct, because all lines have the same slope.
