x - 4y = 8. \r
\n" ); document.write( "\n" ); document.write( "4y= x-8
\n" ); document.write( "y=x/4 -2
\n" ); document.write( "the y intercept is -2 (0,-2)\r
\n" ); document.write( "\n" ); document.write( "passing through (2,4)\r
\n" ); document.write( "\n" ); document.write( "x1 y1 x2 y2
\n" ); document.write( "0 -2 2 4
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "( 4 - -2 )/( 2 - 0 )
\n" ); document.write( "( 6 / 2 )
\n" ); document.write( "m= 3
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point ( 2 , 4 ) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "4.00 = 6 + b
\n" ); document.write( "b= 4 - 6
\n" ); document.write( "b= -2
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y = 3 x -2
