WE NEED TO FIND THE SLOPE OF THIS LINE \n" ); document.write( "3X+5Y=15 \n" ); document.write( "5Y=-3X+15 \n" ); document.write( "Y=-3X/5+15/5 \n" ); document.write( "Y=-3X/5+3 HERE THE SLOPE IS -3/5. (RED LINE) \n" ); document.write( "THEN THE LINE THROUGH (0,9) MUST HAVE A SLOPE OR (-3/5) ALSO TO BE PARALLEL. \n" ); document.write( "NOW SUBSTITUTE THESE (X,Y) VALUES (0,9) & THE SLOPE OF (-3/5) IN THE LINE EAUQTION 7 SOLVE FOR (b) THE Y INTERCEPT OF THIS LINE: \n" ); document.write( "9=-3/5*0+b \n" ); document.write( "b=9 FOR THE Y INTERCEPT OG THIS LINE THAT IS PARALLEL TO THE GIVEN LINE WITH A SLOPE OF (-3/5) & A Y INTERCEPT (b=9) \n" ); document.write( "Y=-3X/5+9 (GREEN LINE) \n" ); document.write( " |
