ANSWER
[tex] \sqrt{5} [/tex]
EXPLANATION
The given points are (1,0) and (0,2).
We use the distance formula:
[tex]d = \sqrt{(x_2-x_1)^2 +(y_2-y_1)^2} [/tex]
We substitute the given points into the formula to get:
[tex]d = \sqrt{(0-1)^2 +(2-0)^2} [/tex]
We simplify to get:
[tex]d = \sqrt{1+4} [/tex]
[tex]d = \sqrt{5} [/tex]
Therefore the distance between the two points is √5 units.
