Question

3. Ir (a/3, 4) is the mid-point of the segment joining the points PC-6,5) and R(-2.3).
then the value of a' is​

Answer 1

Answer:

mid point= (x1+X2/2),(y1+y2/2)

P(-6,5)=(x1,y1)

R(-2,3)=(X2,y2)

mid point is given as (a/3,4)

substitute this values in the given formula

then,we get

(a/3,4)=(-6+(-2)/2),(5+3/2)

a/3=-4/2==-2

4=8/2=4

Therefore,a/3=-2

-2a=3

a=-3/2
