Question 761697
1.Determine whether the lines x-5y=15 and -5x-y+2=0 are parallel, perpendicular, or neither

2. Determine whether the lines y-4=3x and 2y-6x=8 are parallel, perpendicular, or neither
==========================


Solve for y
Then the coefficient of x is the slope.
-----
If the slopes are equal they're parallel.
If the slopes are negative inverses, they're perpendicular.
If neither, they're neither.
