Question
Find the values.
2x + y − 6 = 0
| x | 0 | − 1 | ||
| y | 0 | − 2 |
Solution
Let 2x + y – 6 = 0
(i) x = 0, 2 × 0 + y – 6 = 0
∴ y = 6
(ii) y = 0, 2x + 0 – 6 = 0,
∴ 2x = 6
∴ x = 3
(iii) x = –1, 2 × (–1) + y – 6 = 0, 8 + y = 0
y = 8
(iv) y = – 2, 2x – 2 – 6 = 0, 2x = 8
x = 4
2x + y – 6 = 0
| x | 0 | 3 | −1 | 4 |
| y | 6 | 0 | 8 | −2 |
