Answer:
Proof for 
Step-by-step explanation:
We are given that a, n, b, r and k are integers.
Also,

Since k divides a and b, we can write,
a = rk and b = sk, where r and s are integers.
Now, we have to prove that k divides r as well that is 
Putting value of a and b in the equation, we get:

Since, (r-sn) is an integer, k divides r.
Answer:
y = 8
Step-by-step explanation:
The equation of a line parallel to the x- axis has equation
y = c
where c is the value of the y- coordinates the line passes through.
Then
y = 8 ← is equation of line parallel to the x- axis
