the equation of line
y = -2x - 4
slope of the above line is
y = mx + c
m = - 2 on comparing both,
for parallel line
the slope will be equal, and the line will be pass through (2 , -5).
y -(-5) = m (x - 2)
y + 5 = -2(x - 2)
y + 5 = -2x +4
y +2x +5 -4 = 0
so the equation of new line is
y+2x+1 = 0
or
y = -2x - 1
