Question
Find, which of the following points lie on the line x – 2y + 5 = 0 :
(2, –1.5)
Solution
The given line is x − 2y + 5 = 0.
Substituting x = 2 and y = −1.5 in the given equation, we have:
L.H.S. = 2 − 2 × (−1.5) + 5
= 2 + 3 + 5
= 10 ≠ R.H.S.
Thus, the point (2, −1.5) does not lie on the given line.
