Question

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

(1, 3)

Answer 1

The given line is x − 2y + 5 = 0.

Substituting x = 1 and y = 3 in the given equation, we have:

L.H.S. = 1 – 2 × 3 + 5

= 1 − 6 + 5

= 6 − 6

= 0

= R.H.S.

Thus, the point (1, 3) lies on the given line.
