Question

If ( a/3, 4 ) is the midpoint of the segment joining the points P( -6,5) and R( -2,3) then the value of a is

Answer 1

Answer:

a=12

Step-by-step explanation:

$x1 + x2 \div 2 \: y1 + y2 \div 2$

that's the formula of midpoint...

now -6+(-2)/2,5+3/2

-8/2,8/2

-4,4

But M (a/3,4) is given

then, -4=a/3

a=3+4

a=12

Hope it's right
