Question

Point A is located at (-5, 2). Point B is located at (-5, -3). What is the distance between point A and point B ?

Answer 1

d(A,B) = 5 u.c.

Explanation:

So the formula is:

d(A,B) =
`\sqrt{(x_(B)-x_(A))^(2)+ (y_(B)-y_(A))^(2)` =

Let's substitute.

=
`\sqrt{(-5+5)^(2)+(-3-2)^(2)}` = (Atention to the signals, (-) + (-) = (+)

=√0² + (-5)² = √25 = 5 u.c.

(u.c. means units of compriment)

Answer 2

Answer: The distance is 5 units.

Step-by-step explanation: The x values of the two points are the same. The y values are 5 units apart from each other.
