Algebra.Com's Answer #256817 by mananth(16946)![]() ![]() You can put this solution on YOUR website! I need to find the equation of a line through (-5,4) and parallel to -6x+4y=-7 \n" ); document.write( ".. \n" ); document.write( "If books were very clear then what will teachers do?!!!!! \n" ); document.write( "Anyway \n" ); document.write( "... \n" ); document.write( "the equation -6x+4y=-7 \n" ); document.write( "1.write in slope intercept form \n" ); document.write( "4y=6x-7 \n" ); document.write( "2.compare with equation y = mx+b \n" ); document.write( "slope m= 6 \n" ); document.write( "3. point (-5,4) m=6 \n" ); document.write( "4. find value of b by plugging x,y,m \n" ); document.write( "4=6*-5+b \n" ); document.write( "4=-30+b \n" ); document.write( "b=34 \n" ); document.write( "5. the equation you need is parallel to the given line. \n" ); document.write( "so slope is same. m=6 \n" ); document.write( "6. you have slope,m you have b, plug the values & \n" ); document.write( "write the equation \n" ); document.write( "y=6x+34 \n" ); document.write( "you want to write in general form. bring all terms on one side of the equation. \n" ); document.write( "bring y to the RHS. \n" ); document.write( "6x-y+4=0 is the required equation.\r \n" ); document.write( "\n" ); document.write( "... \n" ); document.write( "m.ananth@hotmail.ca \n" ); document.write( " |
