Answer:

8.49\ units

Step-by-step explanation:

we know that

The Pythagorean Theorem states that in a right triangle

c^2=a^2+b^2

where

c is the greater side (the hypotenuse)

a and b are the legs

In this problem

Let

c=AB ---> distance from point A to point B

a ---> the difference of the x-coordinates both points

b ---> the difference of the y-coordinates both points

so

a=1-(-5)=6\ units\\b=6-0=6\ units

substitute

AB^2=6^2+6^2

AB^2=72

AB=\sqrt{72}\ units

AB=8.49\ units
