Question

If (a/ 3,4) is the mid point of the segment joining the points
P(-6,5) and R(-2,5), then the value of "a" is
a)12
b)-6
c)IS
d)-4​

Answer 1

Step-by-step explanation:

by mid point theorem

$x= \frac{x1 + x2}{2} \\ x= - 6 -( - 2) \div 2 \\ x = \frac{ - 8}{2} \\ x = - 4 \\ x = a = - 4$

Answer 2

Answer:

x= (m2× x1 + m1 × x2)/( m1+ m2)

a/3 = ( 1×-6 + 1 ×-2)/2

a =3×-(8/2)

a = -12
