SLOPE = (Y2-Y1)/(X2-X1)
\n" ); document.write( "(3+3)/(-8-8)
\n" ); document.write( "9/-16
\n" ); document.write( "-9/16 IS THE SLOPE.
\n" ); document.write( "NOW SUBSTITUTE ONE SET OF (X,Y) POINTS AND SOLVE FOR THE Y INTERCEPT(b). THUS:
\n" ); document.write( "-3=-9/16*8+b
\n" ); document.write( "-3=-9/2+b
\n" ); document.write( "b=-3+9/2
\n" ); document.write( "b=-3+4.5
\n" ); document.write( "b=1.5 THUS THE LINE EQUATION IS
\n" ); document.write( "Y=-9/16X+1.5
\n" ); document.write( "
\n" );
