2. Find the distance between A (-1, 4) and B (1.-1)
5.39
5.19
5.29
5.09

Answer 1

Answer: A) 5.39

=====================================================

Step-by-step explanation:

Apply the distance formula.

`d = √( (x_1-x_2)^2+(y_1-y_2)^2)\\\\d = √( (-1-1)^2+(4-(-1))^2)\\\\d = √( (-1-1)^2+(4+1)^2)\\\\d = √( (-2)^2+(5)^2)\\\\d = √( 4+25)\\\\d = √( 29)\\\\d \approx 5.38516\\\\d \approx 5.39\\\\`

You could also use the pythagorean theorem which is what the distance formula is based off of.
