My algebra might be rough but xy=3 is clearly not linear. =p
Now if xy = 3, than y = 3/x
So sub for y
First of all, you don't have a linear equation. The equation is a relative of the inverse function with each element in the range of the function increased by a factor of .
But anyway, the solution is simple.
Solve for either x or y and then substitute.
Now substituting and solving for x
mutiplying bot sides by
and this implies that
Now we have to find all solutions to the equation when
So, the points of importance are
