Question

The coordinate of point A is x and that of B is y then, find d(A,B) if x =-4 and y= -5​

Answer 1

solution :-

D(A,b)=distance between coordinate of A to coordinate of B

IF coordinate of a is x and b is y then d(a,b) =d(x,y)= |x-y| ➠(1)

x=-4 , y=-5

from (1)

therefore , d(a,b)=|-4-(-5)| = |-4+5| => 1

result ➠ 1 .
