Question

Which is the correct formula to find the distance between two points (a, b) and (c, d)? Please Answer quickly! Thank you!

Answer 1

Answer:

Use the distance formula.  Result:  sqrt [ (a-c)^2 + (b-d)^2 ]

Step-by-step explanation:

distance = d = sqrt [ (a-c)^2 + (b-d)^2 ]

Answer 2

Answer:

$d=\sqrt{(c-a)^2+(d-b)^2}$

Step-by-step explanation:

We are given two points (a, b) and (c, d)

We need to find the distance between two points.

It is coordinate of two points. Using coordinate formula of distance.

$d=\sqtt{(x_2-x_1)^2+(y_2-y_1)^2}$

where,

$x_2\rightarrow c$

$x_1\rightarrow a$

$y_2\rightarrow d$

$y_1\rightarrow b$

Substitute into formula

Distance between two points is

$d=\sqrt{(c-a)^2+(d-b)^2}$

Hence, The formula of distance between two points  (a, b) and (c, d) is $d=\sqrt{(c-a)^2+(d-b)^2}$
