You can put this solution on YOUR website! Determine which two equations represent perpendicular lines.
(a) y = 4x – 7
slope is 4
------------
(b) y = x + 7
slope is 1
-------------
(c) y = – x + 7
slope is -1
--------------
(d) y = x – 7
slope is 1
-------------------
c and d are perpendicular
c and b are perpendicular

You can put this solution on YOUR website! YOU HAVE 2 SETS OF PERPENDICULAR LINES
B & C ARE PERPENDICULAR
C & D ARE PERPENDICULAR
BECAUSE THEY ACH HAVE SLOPES (m)THAT ARE NEGATIVE RECIPRICALS OF EACH OTHER:
1 & -1
