FIRST WE FIND THE SLOPE (Y2-Y1)/(X2-X1)=(-7-7)/(4+3)=-14/7=-2 FOR THE SLOPE (m) \n" ); document.write( "NOW SUBSTITUTE X & Y IN THE LINE EQUATION Y=mX+y & SOLVE FOR (b) THE Y INTERCEPT. \n" ); document.write( "7=-3*-2+b \n" ); document.write( "7=6+b \n" ); document.write( "b=7-6 \n" ); document.write( "b=1 Y INTERCEPT. \n" ); document.write( "THEN THE EQUATION IS Y=-2X+1 \n" ); document.write( " |
