(-1,-9)and(-4,-8)
\n" ); document.write( "Y=mX+b where m=the slope & b=the y INTERCEPT.
\n" ); document.write( "m=(Y2-Y1)/(X2-X1)
\n" ); document.write( "m=(-8+9)/(-4+1)=1/-3=-1/3 is this slope.
\n" ); document.write( "-9=-1/3*-1+b
\n" ); document.write( "-9=1/3+b
\n" ); document.write( "b=-9-1/3
\n" ); document.write( "b=(-27-1)/3
\n" ); document.write( "b=-28/3 the Y intercept.
\n" ); document.write( "Y=-X/3-28/3 IS THE LINE EQUATION.
