If A(–2, 3) and B(–3, 5) are two given points then (abscissa of A) – (abscissa of B) = ?

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).
