Algebra.Com's Answer #178429 by oberobic(2304)![]() ![]() ![]() You can put this solution on YOUR website! First, get the equation into y = mx + b format. \n" ); document.write( ". \n" ); document.write( "6y + 9x + 4 = 16 + 9x \n" ); document.write( "Subtract 4 from both sides \n" ); document.write( "6y + 9x = 12 + 9x = 9x + 12 \n" ); document.write( "Subtract 9x from both sides \n" ); document.write( "6y = 12 \n" ); document.write( "Divide both sides by 6 \n" ); document.write( "y = 12/6 = 2 \n" ); document.write( ". \n" ); document.write( "Note that the 'x' term seems to have 'disappeared.' Of course, the x-axis exists, so it cannot 'disappear.' So logically it has to be there, but with a coefficient = 0. \n" ); document.write( ". \n" ); document.write( "y = 0m + 2 \n" ); document.write( ".\r \n" ); document.write( "\n" ); document.write( "So, the slope = m = 0, which means it is a horizontal line. \n" ); document.write( ". \n" ); document.write( "When x = 0, y = 2. (Of course, when x=anything, y=2.) \n" ); document.write( ". \n" ); document.write( "Graph: \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Done. \n" ); document.write( " |
