Check which of the following are solutions of the equations `x-2y=4`and which are not:
(i) `(0,2)` (ii) `(2,0)` (iii) `(4,0)`
(iv) `(sqrt(2),4sqrt(2))` (v) `(1,\ 1)`

Explanation

To determine which of the given points are solutions to the equation \( x - 2y = 4 \), we will substitute each point into the equation and check if the equation holds true.

### Step-by-Step Solution:

1. **Check the point (0, 2):**
- Here, \( x = 0 \) and \( y = 2 \).
- Substitute into the equation:
\[
