First we have to find the slope of the equation. To find the slope we have to do;

The main formula of a line is;

We should use one point to find the real equation. If we use (2,1) point;

a is the slope of the equation, we found that as

So the equation of the line will be;

We can check if our equation is right or not with other given point;

So the equation is correct :)
