Answer 1

Distance formula:
\({\color{blue}{ d(A,B) = \sqrt{(x_B - x_A)^2 + (y_B-y_A)^2} }}\)

Answer 2

We have the points (-2,0) and (2,4)

Answer 3

So if we plug it in we get
\(\begin{aligned}
d(A,B) & = \sqrt{\left( 2 - \left( -2 \right) \right)^2 + \left( 4 - 0 \right)^2} \\ d(A,B) & = \sqrt{ 16 + 16} \\ d(A,B) & = 4 \sqrt{ 2 }
\end{aligned}\)
