Find the slope and y-intercept for each linear equation and determine if the graphs of the pair are parallel, perpendicular, concurrent (but not perpendicular), or coincident.I need help with the last question, I don't know what the lines are.

Find the slope and yintercept for each linear equation and determine if the graphs of the pair are parallel perpendicular concurrent but not perpendicular or co class=

Transform the equations into their slope-intercept form, as shown below

[tex]\begin{gathered} 3y=6x-9 \\ \Rightarrow y=2x-3 \\ and \\ -6x+3y=-9 \\ \Rightarrow y=2x-3 \end{gathered}[/tex]

The slope of both lines is 2 and their y-intercept is -3.

Furthermore, since the equations of both lines are equivalent, the lines are coincident (the same line).

Thus, the answer is coincident.
