Answer: 5 units
Step-by-step explanation:
[tex]Distance = \sqrt{(x_{2 }- x_{1 })^2 + (y_{2 }- y_{1 })^2\\[/tex]
[tex]= \sqrt{(2_ }- (-1)_{ })^2 + (0_{ }- 4_{ })^2[/tex]
[tex]= \sqrt{(2_{ }+ 1_{ })^2 + (-4)^2_[/tex]
[tex]= \sqrt{3^2+(-4)^2}[/tex]
[tex]= \sqrt{9+16}[/tex]
[tex]= \sqrt{25}[/tex]
[tex]= 5 units[/tex]
