is this pair of lines parallel, perpendicular, or neither?

5x - 6y = 19
6x + 5y = -30

You'll need to convert each equation into slope-intercept form [ y=mx +b ].
Then compare the slopes (the coefficient in front of the x variable).
If the lines are parallel then the coeffiecients of each equation will match.
If the lines are perpendicular then one coeffiecient will be the like this...
slope 1:   5/3    Slope 2:  -3/5   <-- the negative inverse of each other.
