Are these two lines parallel, perpendicular, or neither? Explain. #9x+3y=8#, #3x+9y=8#
The given lines are neither parallel nor perpendicular.
To check if two lines are parallel or perpendicular it is good to change the equations to form
The first line is:
The second line is:
From those equations we can see that those lines are neither parallel nor perpendicular
They would be parallel if the coefficients of
They would be perpendicular if the coefficients of
