Determine whether the lines
are parallel, perpendicular, or neither.
-------------------------
Compare the slopes.
2x + 7y = 14
y = (-2/7)x + 2
slope = -2/7
-------------------
y + 2/7x = 6
y = (-2/7)x + 6
slope = -2/7
====================
The slopes are the same so the lines are parallel
==============================
