You have the following points at the coordinate system:

(-1, 3)

(8,-2)

In order to find the distance between the previous points, you use the following formula:

d = √( (x-x_o)² + (y-y_o)² )

By the given cordinates you can take:

x = 8, x_o = -1

y = -2, y_o = 3

By replacing in the formula for the distance you have:

d = √( (8 - (-1))² + (-2 - 3)² )

d = √( (8+1)² + (-5)² )

d = √( 81 + 25 )

d = √(106) ≈ 10.29 ≈ 10.3

Hence, the distance between the points is approximately 10.3
