Decide whether the pair of lines are parallel, perpendicular, or neither. 3x-4y=-3 and 8x+6y=14

Question

precal · Answer

compare slopes
if they are the same then they are parallel
if they are opposite reciprocal then they are perpendicular
if not parallel or perpendicular then they are neither

callisto · Answer

First find the slope of the 2 lines.
If it is in the form Ax+By+C=0, slope = -A/B
If they are // , they have the same slope.
If the product of their slope =-1, they are perpendicular to each other
If they are neither the above case, then it's the choice neither

anonymous · Answer

so are they perpendicular?

callisto · Answer

Yes, I think so
