x1 y1 x2 y2
\n" ); document.write( "4 -2 5 1
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "( 1 - -2 )/( 5 - 4 )
\n" ); document.write( "( 3 / 1 )
\n" ); document.write( "m= 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 = 3 * 8 + b
\n" ); document.write( "1.00 = 24 + b
\n" ); document.write( "b= 1 + -24
\n" ); document.write( "b= -23
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y = 3 x -23
