Point slope equation for point (h,k) and slope m is given by
y-k=m(x-h)
compare given equation with formula
we get h=-7, k=3
so the required point is (-7,3)
For this case we have the following functions:

We must find the following sum of functions:
(f + g) (x)
By definition we have to:

So, we have to:

Answer:
