What is the distance between points
(2,7) and (8, -1)?
A 10
B 25

Answer 1

A. 10

Explanation:

To find the distance between two points you use this equation.

`\sqrt{(x2 - x1)^(2) + (y2 - y1)^(2) }`

Next we replace the values.

`\sqrt{(8-2)^(2) + (-1 - 7)^(2) }`

Next we subtract the values.

`\sqrt{6^(2) + (-8)^2}`

Next we square the values to get 36 and 64.

`√(36 + 64)`

Finally we take the square root of of those two numbers added together.

`√(100)` = 10
