Draw the graph of each of the following linear equations in two variables:
(i) `x+y=4` (ii) `x-y=2`
(iii) `y=3x` (iv) `3=2x+y`

Explanation

To draw the graphs of the given linear equations in two variables, we will follow a systematic approach for each equation.

### (i) Graph of `x + y = 4`

**Step 1:** Create a table of values for x and y.
- Let x = 0, then y = 4 - 0 = 4. So, the point is (0, 4).
- Let y = 0, then x = 4 - 0 = 4. So, the point is (4, 0).
