5. The value of k is the same of b in the original linear equation formula (y=mx+b). The b (or k here) changes where the equation itself fits on the graph. If a +0 is replaced with a -5, then the equation is shifted down by five units. I've graphed it below for you (where f(x) is in red and g(x) is in blue). Hope this helps!
10(1 + 4a) - 7a = -6a + 5(1 + 8a)
10 + 40a - 7a = -6a + 5 + 40a
-40. -40
10 - 7a = -6a + 5
-7a + 6a = 5 - 10
-a = -5
5 = a
