x1 y1 x2 y2
\n" ); document.write( "2 -2 -1 10
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "(10- -2)/(-1 -2)
\n" ); document.write( "( 12 / -3 )
\n" ); document.write( "m= -4
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point ( 2 , -2 ) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "-2.00 = -8 + b
\n" ); document.write( "b= -2 - 8
\n" ); document.write( "b= -10
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y = -4 x -10
