Isolate y in both equations to rearrange in slope intercept
the slope is the coefficient of x
if the coefficients are the same, parallel
if they're negative reciprocals (i.e., multiply to -1), perpendicular
in all other cases, neither
@hot orbit
well the slopes are -2 and 2
which falls under neither
