Answer:

\mathrm{A.\:}x+2y=a

Step-by-step explanation:

In standard form ax+by=c, any point the line passes through will make the inequality true. We can simply use any point given to find the equation of the line:

We can write the following system of equations from two points from the table:

\begin{cases}d\cdot3a+e\cdot(-a)=f\cdot a\\d\cdot5a+e\cdot(-2a)=f\cdot a\end{cases}

Solving, we get:

For a \notin 0,

d=1,\\e=2,\\f=1

Therefore, our equation is:

dx+ey=fa,\\1x+2y=1a,\\\fbox{$x+2y=a$}.
