In order to findthe equation of a line that is parallel to the line we must first determine the slope of the line because parallel lines have the same slope.

In order to find the slope, rewrite the equation in slope-intercept form, 

This makes the slope of the line 1.

The line must pass through the point (1, 2) so we can use point slope form to write the equation of the line.

 If needed to write in slope-intercept form the equation would be:

Though many answers are required to be written in standard form, so this would be:  

The equation of the line that is parallel to x - y = 4 and passes through the point (1, 2) is x - y = -1.
