Algebra.Com's Answer #30791 by checkley71(8403)![]() ![]() ![]() You can put this solution on YOUR website! .1X+.3Y=60 OR .3Y=-.1X+60 OR Y=-.1/.3X+60/.3 OR Y=-1/3X+200 THIS IS THE SLOPE INTERCEPT FORMULA. THE SLOPE IS -1/3 & THE Y INTERCEPT IS 200 ON THE X AXIS. \r \n" ); document.write( "\n" ); document.write( "X REPRESENTS THE HORIZONTAL AXIS OF THE GRAPH & Y REPRESENTS THE VERTICLE AXIS OF THE GRAPH.\r \n" ); document.write( "\n" ); document.write( "I DON'T HAVE GRAPH CAPABILITY. \r \n" ); document.write( "\n" ); document.write( "THE SLOPE OF THIS LINE IS -1/3 AND THIS NEGATIVE SLOPE SAYS THAT FOR EVERY \n" ); document.write( "-3 X UNITS TO THE LEFT THE Y VALUE INCREASES BY 1 UNIT UP. \n" ); document.write( " \n" ); document.write( " |
