Endpoints of a diameter(−2, −1), (2, 1)

Question

i dont understand what to do i ned helpppppp

Answer 1

????????? wotz the quesshun ????????

did teech giv yu sumthun tu find, evaluzte, solv for, kompute, derive?????

Sins the 2 points mark the "diameter", that impli...sumthun about serkel

points: (-2,-1) & (2,1)

deltax=2-(-2)=4

deltay =1 -(-1)=2

length av diameter=root(deltax^2 +deltay^2)

2^2=4 & 4^2=16

sum=20

diameter=root(20)=4.472135955
