Question:
If A(–2, 3) and B(–3, 5) are two given points then (abscissa of A) – (abscissa of B) = ?
(a) –2
(b) 1
(c) –1
(d) 2
Solution:
The given points are A(–2, 3) and B(–3, 5).
Abscissa of A = x-coordinate of A = –2
Abscissa of B = x-coordinate of B = –3
∴ Abscissa of A – Abscissa of B = –2 – (–3) = –2 + 3 = 1
Hence, the correct answer is option (b).
