Answer:
The value of a = 3
Step-by-step explanation:
Given the function

From the attached graph, it is clear that
at x = 0,

∵ 

Thus
When x = 0, the y-intercept will be:

From the attached figure, it is clear that
at x = 0, the value of y = 3
so
putting y = 3 in the equation

3 = a ∵ 
Therefore, the value of a = 3
Answer: the first one is C
the second one is B
Explanation and steps to the expressions are marked in order in the images below.
1. Answer is 3z/2 + 4
2. Answer is 5.8m
3. Answer is n + 5
4. Answer is 15q
5. Answer is 10x + 1/2 + y
6. Answer is 8z + 4.2
The maximum is five images, so I cannot add the last explanation and steps for the last expression.
The next step is to ADD 10x to both sides!
