Question

If A(
௠
ଷ
, 5)is the mid-point of the line segment joining the points Q (– 6, 7) and
R (– 2, 3), then the value of ݉ is

Answer 1

a= -6 b= 7 coordinate of Q

c= -2. d= 3 coordinate of R

x= ? y= 5 coordinate of QR midpoint A

Distance from QA (m)= RA (n)= 1 because A is midpoint

x = (na +mc)/(m+n)

x = (-6(1) + 1(-2))/(1+1)

x= (-6-2)/2

x = -4
