3 x -1 y = 6
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "make y the subject
\n" ); document.write( "-1 y = -3 x + 6
\n" ); document.write( "Divide by -1
\n" ); document.write( " y = 3 x -6
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = 3 0.8
\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 ( 0 , -4 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "-4 = 0.00 + b
\n" ); document.write( "b= -4
\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 -4
\n" ); document.write( " y = 3 x -4
