without graphing, determine which of the following 3 points:
\n" ); document.write( "P1 = (8,6)
\n" ); document.write( "P2 = (2,5)
\n" ); document.write( "P3 = (4,1)
\n" ); document.write( "are part of the graph of the following system:
\n" ); document.write( "y - 10x <= 0
\n" ); document.write( "2y - 3x >= 0
\n" ); document.write( "y + x <= 15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Just substitute the values for the x- and y-coordinates into the inequalities. If all three statements are true for a point, then the point is in the solution set, but if any one of the statements is false, the point is not in the solution set.\r
\n" ); document.write( "\n" ); document.write( "6 - 10(8) <= 0: True
\n" ); document.write( "2(6)-3(8) >= 0: False. Don't bother checking the third inequality, the point P1(8,6) is not in the solution set.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Follow the same procedure for the other two points.
\n" ); document.write( "
\n" );
