Question

A. Find and explain the error in the work shown.

b. Fix the error and show work with the correct result.

Answer 1

The error is that they had placed the numbers in the wrong placeholder. Remember that the Distance formula is
`D=√((x_2-x_1)^2+(y_2-y_1)^2)` .

Correct Work:

`D=√((5-(-1))^2+(16-15)^2)\\D=√(6^2+1^2)\\D=√(36+1)\\D=√(37)\ \approx 6.08`
