(3,5) (9,9)
\n" ); document.write( "Y=mX+b
\n" ); document.write( "m=SLOPE=(Y2-Y1)/(X2-X1)
\n" ); document.write( "m=(9-5)/(9-3)=4/6=2/3 IS THE SLOPE.
\n" ); document.write( "5=2/3*3+b
\n" ); document.write( "5=2+b
\n" ); document.write( "b=5-2
\n" ); document.write( "b=3 ans. for the Y intercept.
\n" ); document.write( "Y=2X/3+3
