Algebra II

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

Step-by-step explanation:

Step 1: Define

Point (-2, -5)

Point (3, -6)

Step 2: Find distance d

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

Substitute in points [DF]: $\displaystyle d = \sqrt{(3--2)^2+(-6--5)^2}$
(Parenthesis) Simplify: $\displaystyle d = \sqrt{(3+2)^2+(-6+5)^2}$
(Parenthesis) Add: $\displaystyle d = \sqrt{(5)^2+(-1)^2}$
[√Radical] Exponents: $\displaystyle d = \sqrt{25+1}$
[√Radical] Add: $\displaystyle d = \sqrt{26}$
