Question

find the distance between the points A(2,3) and
B (4,7)​

Answer 1

Answer:

Step-by-step explanation:

HELLO DEAR,

given vertices are A(2 , 3) , B(4 , 7) and C(0 , -1).

distance formula =  

AB = √{(7 - 3)² + (4 - 2)²} = √(16 + 4) = 2√5.

BC = √{(0 - 4)² + (-1 - 7)²} = √(16 + 64) = 4√5.

AC = √{(3 + 1)² + (2 - 0)²} = √(16 + 4) = 2√5.

therefore, consider BC = AB + AC

4√5 = 2√5 + 2√5 = 4√5

HENCE, A,B,C are collinear.

I HOPE ITS HELP YOU DEAR,

THANKS
