Question

Find the distance between the points (−8, 5) and (7, −3).

Answer 1

17

Explanation:

use distance formula
`\sqrt{(x_1-x_2)^(2)+(y_1-y_2)^(2) }`

`\sqrt{(7-(-8))^(2)+((-3)-5)^(2) }`

simplify

`\sqrt{(7+8)^(2)+(-3-5)^(2) }`

`\sqrt{(15)^(2)+(-8)^(2) }`

`√(225+64)`

`√(289)`

solve the square root

`17`
