(1,6) and (-1,-2)
\n" ); document.write( "Y=mX+b where m=slope & b=the Y intercept.
\n" ); document.write( "m=(Y2-Y1)/(X2-X1)
\n" ); document.write( "m=(-2-6)/(-1-1)
\n" ); document.write( "m=-8/-2
\n" ); document.write( "m=4 is the slope.
\n" ); document.write( "6=4*1+b
\n" ); document.write( "b=6-4
\n" ); document.write( "b=2 the Y intercept.
\n" ); document.write( "Y=4X+2 ans.
