The line x + y = 4 bisects the line segment joining the points (0, k) and (4, 0), the value of k is :

1. 2

2. 4

3. -4

4. -2

Find which of the following points lie on the line x - 2y + 5 = 0 :

(i) (1, 3)

(ii) (0, 5)

(iii) (-5, 0)

(iv) (5, 5)

State true or false :

if the point (2, a) lies on the line 2x - y = 3, then a = 5.

For what value of k will the point (3, -k) lie on the line 9x + 4y = 3?
