Answer:
slope of line y=-3x + 4 (m1) = -3
since the lines are parallel,
So, slope of required line(m) = m1= -3
Now,
Equation of line having slope -3 and passing through (-3, 4) is given by
y - 4 = -3 [ x -(-3) ]
or, y - 4 = -3(x+3)
or, y - 4 = -3x -9
or, y - 4 + 3x + 9 = 0
or, y + 3x + 5 = 0 , which is the required equation.
