Ответ:
First set are parallel, second are perpendicular, third are perpendicular, fourth are neither.
*If you can't remember the rules, or want to check your answers, I would type them into a graphing calculator. It will easily tell you which category they're in. (desmos.com)*
Step-by-step explanation:
1. Same slope (6/5) = parallel
2. Reciprocal (flipped) slope, opposite signs
3. Reciprocal (flipped) slope, opposite signs
4. Neither, the slopes aren't the same or flipped
When you flip the slopes (3/4 becomes 4/3) and change a sign, the lines will always be perpendicular.
Hope it helps :)
