sqrt13

Explanation:

To solve this problem we will use the distance formula:

sqrt((x_2-x_1)^2+(y_2-y_1)^2

We just plug in our two given points.
It doesn't matter which you choice to be (x_2,y_2) or (x_1,y_1)

For this case I'll let point B = (x_2,y_2) and point A = (x_1,y_1)

sqrt((1-(-2))^2+(3-1)^2

sqrt((3)^2+(2)^2 = sqrt(13)
