Answer :

**Concept Used:**

For finding coordinates of a point that lies on a line, put different values of x and obtain different values of y from it.

**Explanation:**

Given line: y = x – 3

At x = 0, y = 0 – 3 = -3

At x = 1, y = 1 – 3 = -2

**Hence, (0, -3) and (1, -2) are two points that lie on y = x – 3.**
