Answer 1

Answer:

2√5

Step-by-step explanation:

Were there answer choices from which to choose?  If so, please share them next time.

The Pythagorean Theorem would suit very well in finding this distance.

The horizontal distance between the two points is 2 (I'm neglecting the - sign), and the vertical distance is 4.  Thus, the distance between the two points is

d = √ [ 2^2 + 4^2 ] = √ [20]  = √4*√5  = 2√5

Answer 2

-2+(-4) i think :)))
