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

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point A (-3, 2)

Point C (-1, 3)

Step 2: Find distance d

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