x1 y1 x2 y2
\n" ); document.write( "9 -14 3 -10
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "( -10 - -14 )/( 3 - 9 )
\n" ); document.write( "( 4 / -6 )
\n" ); document.write( "m= - 2/ 3
\n" ); document.write( "The required line passes through both the points. So we select one point and plug it with the slope
\n" ); document.write( "Plug value of the slope and point ( 8 , 1 ) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "1.00 = - 2/3 * 8 + b
\n" ); document.write( "1.00 = -16/3 + b
\n" ); document.write( "b= 1 + 16/3
\n" ); document.write( "b= 19/ 3
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y = - 2/3 x + 19/3
\n" ); document.write( "Generate values of y from x
\n" ); document.write( "x=2, y = 5 (2,5)\r
\n" ); document.write( "\n" ); document.write( "x=5,y=3 (5,3)\r
