(2,3)(-5,-3)
\n" ); document.write( "Y=mX+b
\n" ); document.write( "m=slope=(y2-y1)/x2-x1)=(-3-3)/(-5-2)=-6/-7=6/7 is the slope.
\n" ); document.write( "3=6/7*2+b
\n" ); document.write( "3=12/7+b
\n" ); document.write( "b=3-12/7
\n" ); document.write( "b=21/7-12/7=9/7 is the y intercept.
\n" ); document.write( "y=6x/7+9/7
