12.21
Explanation:
Step 1: You got to find the distance between your x's
Step 2: You got to find the distance between your y's
Step 3: Apply Pythagorean Theorem: That is do:

So x distance is 10 (I just did 6-(-4))
So y distance is 7 (I just did 8-1 )
As per the formula, I'm going to square both... Then add those squared results together like so 100+49=149
Last step is the square root...
