1 x -1 y = 4
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "make y the subject
\n" ); document.write( "-1 y = - x + 4
\n" ); document.write( "Divide by -1
\n" ); document.write( " y = x -4
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = 1
\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 1
\n" ); document.write( "m= 1 ,point ( -3 , 2 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "2 = -3 + b
\n" ); document.write( "b= 5
\n" ); document.write( "m= 1
\n" ); document.write( "Plug value of the slope and b in y = mx +b
\n" ); document.write( "The required equation is y = x + 5
\n" ); document.write( "
