You can put this solution on YOUR website!
slope, from inspection of
y = –2x – 9
is -2
.
A line parallel must have the same slope.
Plug slope (-2) and (–2, –4) into the "point-slope" form:
y - y1 = m(x - x1)
y - (-4) = -2(x - (-2))
y + 4 = -2(x + 2)
y + 4 = -2x - 4
y = -2x - 8 (this is what they're looking for)
