One meaning of a 'linear' equation is that if you draw the graph 
of the equation, the graph will be a straight line.
That's an easy way to test the equation . . . find 3 points on the
graph, and see whether they're all in a straight line.
This equation is        y  =  4 / x .
To find a point on the graph, just pick any number for 'x',
and figure out the value of 'y' that goes with it.
Do that 3 times, and you've got 3 points on the graph.
Here ... I'll do 3 quick points:
Point-A:  x = 1     y =  4 / 1    =  4
Point-B:  x = 2     y =  4 / 2    =  2
Point-C:  x = 4     y =  4 / 4    =  1
Look at this:
Slope of the line from point-A to point-B 
                         = (change in 'y') / (change in 'x') =  -2 .
Slope of the line from point-B to point-C
                         = (change in 'y') / (change in 'x') =  -1/2 .
The two pieces of line from A-B and from B-C don't even have 
the same slope, so they're not pieces of the same straight line !
So my points A, B, and C are NOT in a straight line.
So the equation is NOT linear. 
Try it again with three points of your own.
