**Statement 1∶**

y = mx + 2

We cannot find anything with statement 1.

**Statement 2∶**

Line passes thgough (2, 1)

We cannot find anything with statement 2.

**Combining statement 1 and 2∶**

∵ Line passes through (2, 1), it will satisfy the equation of line y = mx + 2

∴ Putting x = 2 and y = 1 in the equation of line

⇒ 1 = 2m + 2

⇒ m = -1/2

∴ Both statements 1 and 2 are sufficient.
