Consider the plane which passes through the three points:
(1http://hosted.webwork.rochester.edu/...144/char3B.png−7http://hosted.webwork.rochester.edu/...144/char3B.png−2) , (0http://hosted.webwork.rochester.edu/...144/char3B.png−3http://hosted.webwork.rochester.edu/...144/char3B.png2), and (0http://hosted.webwork.rochester.edu/...144/char3B.png−2http://hosted.webwork.rochester.edu/...144/char3B.png4).
Find the vector normal to this plane which has the form:
( -4,____ ,_____ )
Thanks.
