Question:
If the coordinates of the two points are P(-2, 3) and Q(-3, 5), then (Abscissa of P) – (Abscissa of Q) is
(a)-5
(b) 1
(c)-1
(d) -2
Solution:
(b) We have, points P(- 2, 3) and Q(- 3, 5)
Here, abscissa of Pi.e., x-coordinate of Pis -2 and abscissa of Q i.e., x-coordinate of Q is -3. So, (Abscissa of P) – (Abscissa of Q) = – 2 – (-3) =-2 + 3=1.
