The equation \( y = 3x - 2 \) represents a linear relationship.
In general, a linear relationship can be expressed in the form:
\[ y = mx + b \]
where \( m \) is the slope (in this case, 3) and \( b \) is the y-intercept (in this case, -2).
Since this equation can be rearranged to fit the linear form, it is indeed a linear relationship. The graph of this equation would be a straight line.
