The distance would be 5
Step-by-step explanation:
You would have to use the distance formula, which is:

The coordinate 2 is
and coordinate -1 is 
And the coordinate 0 is
and 4 is 
So now we would put those values into the formula as follows:

According to PEMDAS, we would have to evaluate parenthesis first
*Keep in mind that two negative signs equal a positive

Following with PEMDAS, we'll now square both numbers

Evaluate

And simplify
