x1 y1 x2 y2
\n" ); document.write( "-4 7 8 16
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "( 16 - 7 )/( 8 - -4 )
\n" ); document.write( "( 9 / 12 )
\n" ); document.write( "m= 3/ 4
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point ( -4 , 7 ) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "7.00 = -3 + b
\n" ); document.write( "b= 7 - 3
\n" ); document.write( "b= 4
\n" ); document.write( "So the equation will be
