points given are
(1,1)
(5,6)
x1=1
y1=1
x2=5
y2=6
D=\sqrt{(1-5)^{2}+(1-6)^{2}}
D=\sqrt{(-4)^{2}+(-5)^{2}}
D=\sqrt{16+25}

Use the distance formula to find the distance between two points.
D= \sqrt{(x2-x1)^2+(y2-y1)^2}
The points are (5, 6) and (1, 1)
D= \sqrt{(5-1)^2+(6-1)^2}
D= \sqrt{4^2+5^2}
D= \sqrt{16+25}
D= \sqrt{41}
\sqrt{41} is about 6.4

B. 6.4 units

Hope this helps :)
