Answer 1

Answer:

Step-by-step explanation:

(a,b) is the mid-point of Line segment joining the points A(10,−6) and B(k,4)

So,

a=  

2

10+k

​  

  and  b=  

2

−6+4

​  

=−1

It is given that,

a−2b=18

Put b=−1

a−2(−1)=18

a=18−2=16

Now,

a=  

2

10+k

​  

 

16=  

2

10+k

​  

 

k+10=32

k=22

Distance between the points (x

​  

,y

​  

) is

​  

 

Distance between the points (10,−6)  and  (22,4) is

(22−10)
