Answer:

Explanation:
( I think, if this is not correct please let me know)

So the formula is on there and all you have to do is fill in the Xs and Ys.

Square root of (-4 - 2)^2 + (7 - 1)^2

Solve inside parentheses:

(-6)^2 + (6)^2

Square the numbers

36 + 36

Add

72

Now we have to find the square root of 72, which is about 8.5 ( rounded to the nearest tenth )
