Are these two separate questions?
Answer:
Step-by-step explanation:

Option A is correct.
Put the values of x in 3^x and you will get the answer corresponding to option A
Its A because 25 is taken out of m=bday money m-$25
First using the given two points we can find the slope (m) of the line

Thus the slope of given line is 1.
Using slope and a point (0,1) we can write the equation in point slope form as
y - 1= 1(x-0)
y - 1 = x
The above equation is the point-slope form of the equation.
