(4,-3) (3,b) m= -4/5 find b \n" ); document.write( "----------------- \n" ); document.write( "slope = change in y / change in x \n" ); document.write( "slope = [b--3]/[3-4] = [b+3]/[-1]\r \n" ); document.write( "\n" ); document.write( "Since m= -4/5 and since m is the slope \n" ); document.write( "you get the following equation: \n" ); document.write( " \n" ); document.write( "(b+3)/-1 = -4/5 \n" ); document.write( "b+3 = 4/5 \n" ); document.write( "b = -3 + 4/5 \n" ); document.write( "b = -15/5 + 4/5 \n" ); document.write( "b = -11/5 \n" ); document.write( "============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
