You can put this solution on YOUR website!
Parallel lines have identical slopes.
Perpendicular lines have slopes that are negative reciprocals.
Vertigo is what you get when you do too many problems.
Vercengeterix used algebra to conquer the Roman empire.

5x%2B4y=-60
4y=-5x-60
y=-%285%2F4%29x-60
So,
m%5B1%5D=-5%2F4
m%5B2%5D=-4%2F5
So they're neither perpendicular not parallel.

Do the second one the same way.
The slope of the first equation is,
x%2B6y=196
6y=-x%2B196
y=-x%2F6%2B98%2F3
So,
m%5B1%5D=-1%2F6
Find the slope of the second line similarly and then compare.
