Solve the equation for y to find the equation of the line in slope intercept form.
[tex]\begin{gathered} -3y=-9 \\ y=\frac{-9}{-3} \\ y=3 \end{gathered}[/tex]
According to the equation, the line represents a constant function, which means that for any value of x, y is always 3. For example, 2 ordered pairs of this line would be (1,3) and (4,3). Graph the line:
