1 y = -3 x -1
\n" ); document.write( "Divide by 1
\n" ); document.write( " y = -3 x -1
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = -3
\n" ); document.write( "The slope of a line parallel to the above line will be the same
\n" ); document.write( "The slope of the required line will be -3
\n" ); document.write( "m= -3 ,point ( -2 , -1 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "-1 = 6 + b
\n" ); document.write( "b= -7
\n" ); document.write( "m= -3
\n" ); document.write( "Plug value of the slope and b in y = mx +b
\n" ); document.write( "The required equation is y = -3 x -7
\n" ); document.write( "
