Answer 2

Answer: 5

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

Explanation

I'll use the distance formula.

`(x_1,y_1) = (1,3) \text{ and } (x_2, y_2) = (-2,7)\\\\d = √((x_1 - x_2)^2 + (y_1 - y_2)^2)\\\\d = √((1-(-2))^2 + (3-7)^2)\\\\d = √((1+2)^2 + (3-7)^2)\\\\d = √((3)^2 + (-4)^2)\\\\d = √(9 + 16)\\\\d = √(25)\\\\d = 5\\\\`

The distance is 5 units.
