One way of thinking
about this problem is that we are looking for the intersection of two equations:
1.
y=x+2/3
2.
y=4/x+1
The first equation
is a straight line:
The second equation
is a hyperbola:
If we overlay the
two equations, we can see where they intersect:
If we rearrange the
terms, we can restate the equation as follows: 3x2-x-12=0. This
describes a parabola:
The points of
intersection are as follows:
