find the value of k for which point P(a/3‚2) is the midpoint of the line segment joining the points Q(-5‚4) and R(-1‚0)
TheGirlOnFire:
there isn't a k in the question... did you mean a?

P(a/3,2)= midpoint of QR
P(a/3,2)=(-5-1/2,4+0/2)
P(a/3,2)=(-6/2,4/2)
P(a/3,2)=(-3,2)
equating both sides
a/3 = -3
a = -3×3
a = -9 is answer obtained
