Are the following lines parallel, perpendicular, or neither? L1 with equation x – 5y = 10 L2 with equation 5x + y = 5
---------
Put both in slope-intercept form:
L1: 5y=x-10
y=(1/5)x-2
slope is 1/5
------------
L2: y=-5x+5
slope is -5
---------------
L1 and L2 are perpendicular to each other because the sole of
one is the negative reciprocal of the other.
