Algebra.Com's Answer #26977 by tutorcecilia(2152)![]() ![]() You can put this solution on YOUR website! I would put each equation in the slope-intercept format: y = mx + b. \n" ); document.write( "Than graph both equations. Note their common points.\r \n" ); document.write( "\n" ); document.write( "y = mx + b really means to solve for y.\r \n" ); document.write( "\n" ); document.write( "x - y = 2 \n" ); document.write( "-y = -x +2 \n" ); document.write( ". \n" ); document.write( "(-1)y/(-1)=-x/(-1) + 2/(-1) \n" ); document.write( ". \n" ); document.write( "y = x - 2 \n" ); document.write( "Graph this equation. \n" ); document.write( ". \n" ); document.write( "Solve for y in the second equation: \n" ); document.write( "3x - 3y = 6 \n" ); document.write( "-3y = -3x + 6 \n" ); document.write( ". \n" ); document.write( "-3y/-3 = -3x/-3 + 6/-3 \n" ); document.write( ". \n" ); document.write( "y = x - 2 \n" ); document.write( "Graph this equation.\r \n" ); document.write( "\n" ); document.write( "Notice that the equations are the same so they are the same line with all points in common. \n" ); document.write( " \n" ); document.write( " |
