Graph the inequality: \r
\n" ); document.write( "\n" ); document.write( " $\"-1%3Cy%2B5x%3C=11\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"-5x-1%3Cy%3C=-5x%2B11\"$ \r
\n" ); document.write( "\n" ); document.write( "first graph two lines, $\"-5x-1=y\"$ and $\"y=-5x%2B11\"$ \r
\n" ); document.write( "\n" ); document.write( "you need two points to graph each line\r
\n" ); document.write( "\n" ); document.write( " $\"-5x-1=y\"$ if $\"x=0\"$ -> $\"-1=y\"$ =>point:( $\"0\"$ , $\"-1\"$ )\r
\n" ); document.write( "\n" ); document.write( " $\"-5x-1=y\"$ if $\"yx=0\"$ -> $\"5x=-1\"$ -> $\"x=-1%2F5\"$ =>point:( $\"-1%2F5\"$ , $\"0\"$ )\r
\n" ); document.write( "\n" ); document.write( "second line\r
\n" ); document.write( "\n" ); document.write( " $\"y=-5x%2B11\"$ if $\"x=0\"$ -> $\"y=11\"$ =>point:( $\"0\"$ , $\"11\"$
\n" ); document.write( " $\"y=-5x%2B11\"$ if $\"y=0\"$ -> $\"5x=11\"$ -> $\"x=11%2F5\"$ =>point:( $\"11%2F5\"$ , $\"0\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "plot points and draw lines through:\r
\n" ); document.write( "\n" ); document.write( "

\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since you need $\"-5x-1%3Cy%3C=-5x%2B11\"$ , left line on graph above should be dashed because that one is NOT part of solution, right line IS part of solution\r
\n" ); document.write( "\n" ); document.write( "your solution will be area between these lines including a line to the right (shade it), like this\r
