2. On the grid below, what is the distance between points A and B?

Its 11.31 or

Step-by-step explanation:

So the distance formula is d=√((x_2-x_1)²+(y_2-y_1)²).

Point A is (-2,2) and Point B is (6,-6).

So then we replace the numbers

d=√(6+2)²+(-6-2)²

d=√(8)²+(-8)²

d=√64+64.

d=√128.

d=11.31
