Question

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

(–5, 0)

Answer 1

The given line is x − 2y + 5 = 0.

Substituting x = −5 and y = 0 in the given equation, we have:

L.H.S. = −5 − 2 × 0 + 5

= −5 − 0 + 5

= 5 − 5

= 0 = R.H.S.

Thus, the point (−5, 0) lie on the given line.
