Answer & Step-by-step explanation:
For this problem, we will use the distance formula.
![d=\sqrt{(x2-x1)^2+(y2-y1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x2-x1%29%5E2%2B%28y2-y1%29%5E2%7D)
For our (x1, y1), we will use (-3, 1). For our (x2, y2), we will use (1, 5). Now let's plug in our numbers and solve the problem.
![d=\sqrt{(1-(-3))^2+(5-1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%281-%28-3%29%29%5E2%2B%285-1%29%5E2%7D)
![d=\sqrt{4^2+4^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B4%5E2%2B4%5E2%7D)
![d=\sqrt{16 + 16}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B16%20%2B%2016%7D)
![d=\sqrt{32}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B32%7D)
![d=5.657](https://tex.z-dn.net/?f=d%3D5.657)
So, the distance between (-3,1) and (1,5) is 5.657 units.
