Question

8.
If P(-2,3) and Q(-3,5) are the points on the Cartesian plane then find following
a) The sum of one-third of ordinate of P and two- fifth ordinate of Q.
b) 2 (Abscissa of P) + Abscissa of Q​

Answer 1

ordinate means y-co ordinate

abscissa means x-coordinate

a). 1/3(3) = 1. [ordinate of p= 3]

2/5(5) =2. [ordinate of Q is 5 ]

b) 2 ( -2) + (-3) = -7 [ abscissa of P is -2 & abscissa of Q is -3 ]
