It is linear if it just has an x term, but no x², x^3, etc.
If you can get it in the form:
y = mx + b
Then it is linear.
Examples of linear equations:
y = 2x + 3
y = -7x - 4
4 + y = 2x
(4 + y)/2 = x
*Last two can be changed into y = mx + b form...
Examples of non-linear equations:
y = x² + 2x + 1
y = x^3 - 7
y = sqrt(x)
etc.

linear equations have the following form
ax+ by +c =0

An equation is linear if there is are only two variables, dependant and independant (y and x respectively) and each variable is raised to a power of 1.

a linear eq is one that does not have any variables with power greater than 1
y = 3x + 2 is linear
y = 3x^2 + 2 is not

if the x-variable in the equation isn't raised to any power or dividing into anything then it is linear...
all these forms are linear:
y = mx+b
ax+by = c
(y-y1) = m(x-x1)

if it's a linear equation it's in y-intercept form: y=mx+b
