Question

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

(5, 5)

Answer 1

The given line is x − 2y + 5 = 0.

Substituting x = 5 and y = 5 in the given equation, we have:

L.H.S. = 5 − 2 × 5 + 5

= 5 − 10 + 5

= 10 − 10

= 0 = R.H.S.

Thus, the point (5, 5) lies on the given line.
