The slope of a line parallel to the line whose equation is 9x -3y = -54 has the same slope . To solve for the slope we can find y by using the following formula

[tex]\begin{gathered} y=mx+b \\ m=slope \\ b=y\text{ intercept} \\ y=mx+b \\ 9x-3y=-54 \\ 9x-9x-3y=-54-9x \\ -3y=-54-9x \\ \frac{-3y}{-3}=\frac{-54}{-3}+\frac{-9x}{-3} \\ y=18+3x \\ \end{gathered}[/tex]

The slope of the line parallel to the line = 3
