Find the distance that the points is given on the graph ?

From the graph, the given points are (2,-1) and (4,0). Use the distance between two points formula:
[tex] \large \boxed{ \sqrt{ {(x_2 - x_1)}^{2} + {(y_2 - y_1)}^{2} } }[/tex]
Substitute these points in the formula.
[tex] \large{ \sqrt{ {(2 - 4)}^{2} + {( - 1 - 0)}^{2} } } \\ \large{ \sqrt{ {( - 2)}^{2} + {( - 1)}^{2} } } \\ \large{ \sqrt{4 + 1} \longrightarrow \sqrt{5} }[/tex]
Hence, the distance is √5
