Question

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

Answer 1

Answer:

5

Step-by-step explanation:

-2 - (-7)

-2 + 7

= 5

Answer 2

Answer:

5

Step-by-step 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
