Answer: About 6.71 units

Step-by-step explanation:

You use the distance formula: \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}  }.

Assign the the two points to the variables:

(x_{1}, y_{1}) =  (1, 3)\\(x_{2}, y_{2}) = (4, -3)

Substitute them in the formula:

\sqrt{(4-1)^{2}+(-3-3)^{2}}

And solve it:

\sqrt{(4-1)^{2}+(-3-3)^{2}}\\=\sqrt{(3)^{2}+(-6)^{2}}\\=\sqrt{9+36}\\=\sqrt{45}\\=6.71
