Question

If p(a,b) is the midpoint of a line segment joining a(10,-6) and b(k,4) and a-2b =18. Find the value of k and the distance of ab ?
Answer plz​

Answer 1

Answer:

22

√244

Step-by-step explanation:

(10+k)/2. ,(-6+4)/2

a= 10+k/2

2a=10+k

k=2a-10

a-2b=18

b= -1

a=18+2b=18-2=16

k=2*16-10=22

distance=√244=15.62
