Answer 1

b

Step-by-step explanation:

Answer 2

The two functions that defines the situation are :
f(x) = x + 5
and
f(x) = x + 8

When you plug in different values of x and graph the coordinates,you will notice that the graph as been shifted 3 units up.
So,
The best answer is :
B. the line will shift vertically up by $3.
