### What is the graph of the equation?

The graph of an equation is all of the answers that are true for
the equation.
A variable is an unknown number in an equation. Most equations
are written with x and y variables. There are an unlimited amount
of numbers that the variables can be to have the equation be true,
so you would graph the equation to show the unlimited amount of
numbers that make the equation true.

### When does the nonlinear equation becomes linear equation?

A linear equation is defined as an equation that contains only
the first power of the unknown quantity.
For example, 5x - 3 = 7 where "x" is the unknown quantity is a
linear equation.
If an equation contains an unknown quantity having a higher
power than 1, then the equation ceases to be a linear equation.
For example, 3x2 + 5x + 7 = 0 is a non linear equation known as
a quadratic equation, because the unknown quantity "x" has a power
of 2.
Similarly, equations containing unknowns with higher powers such
as x3, x7, x12 are all non linear equations.
