The answer is: `3xy=6` is not a linear equation.
Solving for y we get the function:
`y=2/x` or `y=2x^-1` , x is at the -1 power.
The general form of a linear equation is `ax+b=c`, or expressed as a function `y=ax+b` and the graph is a line. x is at the power of 1
In this case `y=2x` would be a linear equation.
See the graphs below:
If y = f(x) represents a linear equation it can be written as y = ax + b where a and b are constants.
y = 6/(3x)
y = 2/x
It can be seen that the value of y is not directly proportional to that of x, rather y and x are inversely proportional to each other. As the value of x increases, the value of y decreases and as the value of x decreases the value of y increases.
3*x*y = 6 is not a linear equation.
This is clearly shown in the graph of y versus x.
3xy=6 would not be a linear equation. Usually, a linear equation will follow the form y=mx+b. If we change your equation so we have it in terms of y, then it would be:
y=6/3x, or simplified to:
As you can see, that doesn't comply with y=mx+b.
Also, linear equations must produce linear lines on a graph. If we graph out y=2/x, we see that this is not the case.
