Question 59678
yes,  y=3x-2 is a linear equation.

explanation:

A linear equation is an equation involving only the sum of constants or products of constants and the  FIRST POWER  of a variable. Such an equation is equivalent to equating a first-degree polynomial to zero. These equations are called "linear" because they represent straight lines in Cartesian coordinates. 

a linear equation in one varible means which contains only one variable.fo example, 6x+3=7  and its general form is ax +b =0, where a and b are constants.

a linear equation in two varibals means which contains two variables.
for example,

 y = 3x + 5    
the general for of a linear equation in two variable is y=ax+b, where a and b are constants.
