Algebra.Com's Answer #6505 by chicosgurrl(2)![]() ![]() ![]() You can put this solution on YOUR website! The formula for slope-intercept is : \n" ); document.write( ". \n" ); document.write( "y=mx+b \n" ); document.write( ". \n" ); document.write( "so, they gave you 3y+x-9=0 \n" ); document.write( "so make it look like the slope intercept form by getting Y on one side of the equal sign. \n" ); document.write( ". \n" ); document.write( "In order to do that you need to subtract x and add 9 to both sides:\r \n" ); document.write( "\n" ); document.write( "3y+x-9=0 \n" ); document.write( "-x+9=-x+9 \n" ); document.write( "_________\r \n" ); document.write( "\n" ); document.write( "3y=-x+9 ...but the Y must be by itself so divide both side by 3: \n" ); document.write( ". \n" ); document.write( "y= -1/3x+3...(final answer) \n" ); document.write( ". \n" ); document.write( "so that is how to put it into slope intercept form.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
