Algebra.Com's Answer #44389 by checkley71(8403)![]() ![]() ![]() You can put this solution on YOUR website! WHAT YOU HAVE IS A STANDARD LINE FORMULA Y=mX+b WHERE m=THE SLOPE (-1/2) & b=THE Y INTERCEPT (0,3). \n" ); document.write( "THE SLOPE IS FOUND BY THE FOLLOWING FRACTION (Y2-Y1)/X2-X1). \n" ); document.write( "TO FIND A SECOND POINT USING THIS EAUATION WE SET Y=0 & SOLVE FOR X THUS \n" ); document.write( "0=-1/2X+3 \n" ); document.write( "1/2X=3 \n" ); document.write( "X=3*2 \n" ); document.write( "X=6 OR (6,0) \n" ); document.write( "NOW PLOTING THESE TWO POINTS (0,3) &(6,0) & DRAWING A LINE THROUGH THEM YOU HAVE A SLOPE OF -1/2. \n" ); document.write( "HAPPY GRAFTING :) \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
