Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point A (2, -1)

Point B (-4, 2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(-4-2)^2+(2+1)^2}$
Subtract/Add: $d = \sqrt{(-6)^2+(3)^2}$
Exponents: $d = \sqrt{36+9}$
Add: $d = \sqrt{45}$
Simplify: $d = 3\sqrt{5}$
