Answer:
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:
![\sqrt{ (\text{ distance of x})^2+( \text{ distance of y})^2}\\](https://img.qammunity.org/2020/formulas/mathematics/middle-school/l4srzuivmvm1x938cdlfj9rbekvwsogbr3.png)
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...
![√(149) \approx 12.21](https://img.qammunity.org/2020/formulas/mathematics/middle-school/pwygk6iy9j29a0c6bafyh01c56upgr8hmk.png)
