A linear equation is any equation that can be written in the form

 

where a and b are real numbers and x is a variable.  This form is sometimes called the standard form of a linear equation.  Note that most linear equations will not start off in this form.  Also, the variable may or may not be an x so don’t get too locked into always seeing an x there.
