==========================
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.

1.Determine whether the lines x-5y=15 and -5x-y+2=0 are parallel, perpendicular, or neither
x-5y=15
y = (1/5)x - 3
slope = 1/5
--------------------
-5x-y+2 = 0
y = -5x + 2
slope = -5
-----
Since (1/5)(-5) = -1 the lines are parallel.
==================================================
2. Determine whether the lines y-4=3x and 2y-6x=8 are parallel, perpendicular, or neither
y-4=3x
y = 3x + 4
slope = 3
---------------------
2y-6x = 8
y = 3x+4
slope = 3
-------
Since the two equations are the same the lines are neither.
