Question

5. If (4, 0) is the mid point of the line joining (-8, 13) and (x,7), then find the value of x.​

Answer 1

Answer:

Given : A(−8,13)B(x,7) are points.

Midpoint  = P(4,10)

Answer 2

Step-by-step explanation:

SOLUTION

We are given a line which joins the two distinct points (-8,13) and (x,7) and the mid point of this line is given as (4,0).

THEORY

As we know that the mid point of a line joining points (x1,y1) and (x2,y2) can be given as

X=[x1+x2/2] Y=[y1+y2/2]

PROCEDURE

(4) = [x-8/2]

x= 16
