Equation of a ray on the Argand plane

Argand plane with axes from −3 to 3 showing a ray starting at an open circle at (−2, 3), passing through (0, 1) and (1, 0), and continuing down to the right with an arrow, at an angle of −π/4 to the positive real direction.

The equation of the ray on the Argand plane above is
