Sure it can. If a single linear equation has two variables, then it defines not one solution, but many solutions. If you plot the solutions on a graph, where one axis is one variable and another axis is another variable, you get a straight LINE. That's why the equation is called LINEar.
Example of a linear equation with two variables: y-x=3. Its graph:
