Question

Uh I'm confused on how to do this may someone help?

Answer 1

5

Explanation:

-2 - (-7)

-2 + 7

= 5

Answer 2

5

Explanation:

Use the distance formula

`\sqrt{(x_(1)-x_(2))^(2)+(y_(1)-y_(2))^(2)}`

`\sqrt{(-2+7)^(2)+(4-4)^(2)}`

`\sqrt{5^(2)}=5`

You can also just subtract: -2-(-7) to get 5 because the y-values are the same
