Question

Find the distance between the pair of points A(-1,8) and B(-8,4)​

Answer 1

Answer:

$\sqrt{65}$

Step-by-step explanation:

Solve using the distance formula:

$d = \sqrt{(x2 - x1)^2+(y2 - y1)^2}$

Input the corresponding numbers into the formula

$d = \sqrt{(-8 - (-1))^2+(4-8)^2}$

Solve

$d = \sqrt{49+16}\\ d =\sqrt{65}$
