You can put this solution on YOUR website!
Given: \"y+%3C=+%281%2F4%29x+-1+\"\r
\n" ); document.write( "\n" ); document.write( "You are asked to graph this.\r
\n" ); document.write( "\n" ); document.write( "The easiest way to graph a function like this is to graph the equality first.\r
\n" ); document.write( "\n" ); document.write( "\"y+=+%281%2F4%29x+-1\" This is in the form y = mx + b. So you know it is a line with slope 1/4 and y intercept of -1.\r
\n" ); document.write( "\n" ); document.write( "So graph that as
\n" ); document.write( "\"graph%28600%2C+400%2C+-10%2C+10%2C+-10%2C+10+%2C+%281%2F4%29x-1%29\"\r
\n" ); document.write( "\n" ); document.write( "That line is the equality. So where in the graph is y \"less than\"? All points that fall below the line are points where y < (1/4)x -1.\r
\n" ); document.write( "\n" ); document.write( "So just cross hatch the area below the line and leave the line as is.\r
\n" ); document.write( "\n" ); document.write( "If you had been asked to graph y<(1/4)x -1 that is, without the equal sing included, you would proceed the same way as above EXCEPT, you would draw the original line in using a dotted line. Dotted line tells the person reading your plot that the graph's solutions to NOT include the line itself .. jus the area below it.\r
