Final answer:
The differential equation that corresponds to the given direction field y' = x - y is y' = x - y.
Step-by-step explanation:
To find a differential equation that corresponds to a given direction field, we need to determine the equation that gives the slope of the tangent line at each point.
For the direction field y' = x - y, the slope is given by the expression x - y. Therefore, the differential equation is y' = x - y.
