Question

2.
Find the value of x for which point A ( x/2,2 ) is the mid point of the line segment joining the
points (-5,4 ) and R (-1,0)

Answer 1

Answer:

Coordinates of midpoint are (x,y)

x=2(x1+x2)

y=2(y1+y2)

According to the question:

x=2−5−1=−3

⇒3a=−3

⇒a=−9

y=2(4+0)=2

coordinate of mid point =(−3,2)

so, a=−9
