Answer:
4.2 units
Step-by-step explanation:
Assuming 1 grid box = 1 units, the coordinates of the two points are (-1, -1) and (2, 2).
Apply distance formula 
to find the distance between (-1, -1) and (2, 2).
Let,
Plug in the values
(to the nearest tenth)
1 equals 0.46 (make a line over the 6 to show it is repeated)
2 equals 0.4 (make a line over the 4 to show it is repeated)
3 equals -0.6 (make a line over the 6 to show it is repeated)
4 equals -0.857142 (make a line over all numbers past the decimal to show it is repeated)
5 equals 3.3409 (make a line over the 09 at the end to show it is repeated)
6 equals -1.7727 (make a line over the 27 at the end to show it is repeated)
7 equals 66.5%
8 equals 3.16 (make a line over the 6 to show it is repeated)
9 equals -9 over 10
10 equals -17 over 20
11 equals -3 and 4 over 5
