Question

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

Answer 1

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

Answer 2

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

Answer 3

so are they perpendicular?

Answer 4

Yes, I think so
