Algebra.Com's Answer #342585 by richard1234(7193)![]() ![]() You can put this solution on YOUR website! 1. You're right. Three collinear points determine a line, not a plane.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2. \"Sometimes\" is right, if the two points are located at the same place you cannot determine a line.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "3. \"Always\" is right, because a plane contains an infinite number of lines. \n" ); document.write( " |
