the way to graph y=5/4x:
\n" ); document.write( "set y=0 and solve for x.
\n" ); document.write( "0=5/4x
\n" ); document.write( "x=0 or this defines the point (0,0)
\n" ); document.write( "now set y to any other number like 4 & solve for x;
\n" ); document.write( "4=5/4xnow cross multiply
\n" ); document.write( "4*5/4=x
\n" ); document.write( "x=20/4
\n" ); document.write( "x=5 or point (5,4)
\n" ); document.write( "y=5x/4 (red line)
\n" ); document.write( "2y-5x=-2
\n" ); document.write( "2y=5x-2
\n" ); document.write( "y=5x/2-2/2
\n" ); document.write( "y=5x/2-1 (green line)
\n" ); document.write( " $\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+5x%2F4+%2C+y+=+5x%2F2+-1%29+\"$ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = 5x/4 and y = 5x/2 -1). \n" ); document.write( "
