Answer 2

`d=3\ units`

Explanation:

The distance formula is:

`d = \sqrt {\left( {x_2 - x_1 } \right)^2 + \left( {y_2 - y_1 } \right)^2`

We can plug in the given coordinate pairs into the formula:

`d = \sqrt {\left( {5-5\right)^2 + \left( {4-(-1) } \right)^2`

`d = \sqrt {\left( {0 } \right)^2 + \left( {-4+1} \right)^2`

`d=√(0+(-3)^2)`

`d=√(0+9)`

`d=√(9)`

`d=3\ units`
