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.
