Algebra.Com's Answer #178868 by richwmiller(17219) You can put this solution on YOUR website! Graph the following line 8x-y=-9 \n" ); document.write( "It is generally easiest to calculate points where x=0 and y=0 \n" ); document.write( "It is easiest if x and y are whole numbers \n" ); document.write( "and in desperate times try x=1 and y =1\r \n" ); document.write( "\n" ); document.write( "so \n" ); document.write( "if x=0 then -y=-9 :multiply by -1: y=9 \n" ); document.write( "if y=0 then 8x=-9 x=-9/8 \n" ); document.write( "if y=1 then 8x-1=-9 \n" ); document.write( "add one to both sides \n" ); document.write( "8x=-8 \n" ); document.write( "x=-1 \n" ); document.write( "so plot x=0 and y=9 \n" ); document.write( "and y=1 and x=-1 \n" ); document.write( " |
