FIRST YOU NEED TO FIND THE SLOPE(m).
\n" ); document.write( "SLOPE=(Y2-Y1)/(X2-X1)
\n" ); document.write( "SLOPE=(3-1)/(3-1)=2/2=1 FOR THE VALUE OF THE SLOPE
\n" ); document.write( "NOW REPLACE ONE SET OF (X,Y) VALUES FOR THE X & Y IN THE STANDARD LINE FORMULA:
\n" ); document.write( "Y=mX+b ALONG WITH THE SLOPE(m)=1 & SOLVE FOR THE Y INTERCEPT(b)
\n" ); document.write( "1=1*1+b
\n" ); document.write( "1=1+b
\n" ); document.write( "b=1-1
\n" ); document.write( "b=0
\n" ); document.write( "SO WE HAVE THE LINE EQUATION:
\n" ); document.write( "Y=1X+0 OR Y=X
\n" ); document.write( "THE GRPAH OF THIS LINE FOLLOWS:
\n" ); document.write( "\"+graph%28+300%2C+300%2C+-6%2C+6%2C+-6%2C+6%2C+y+=+x%29+\" (graph 300x300 pixels, x from -6 to 6, y from -6 to 6, y = x).
