(5,2) (x,-2)\r
\n" ); document.write( "\n" ); document.write( "m=2\r
\n" ); document.write( "\n" ); document.write( "2= (-2-2)/(x-5)\r
\n" ); document.write( "\n" ); document.write( "2(x-5)=-4
\n" ); document.write( "2x-10=-4
\n" ); document.write( "2x=6
\n" ); document.write( "x=3\r
\n" ); document.write( "\n" ); document.write( "Plug value of the slope and point( 5 , 2 ) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "2.00 = 10 + b
\n" ); document.write( "b= 2 - 10
\n" ); document.write( "b= -8
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y = 2 x -8
\n" ); document.write( " \n" ); document.write( "
