- Distance Formula: [tex]\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Step-by-step explanation:
Step 1: Define
Find points from graph.
Point R(-2, -4)
Point S(-8, -6)
Step 2: Find distance d
Simply plug in the 2 coordinates into the distance formula to find distance d
- Substitute in points[DF]: [tex]\displaystyle d = \sqrt{(-8+2)^2+(-6+4)^2}[/tex]
- (Parenthesis) Add: [tex]\displaystyle d = \sqrt{(-6)^2+(-2)^2}[/tex]
- [√Radical] Exponents: [tex]\displaystyle d = \sqrt{36+4}[/tex]
- [√Radical] Add: [tex]\displaystyle d = \sqrt{40}[/tex]
- [√Radical] Simplify: [tex]\displaystyle d = 2\sqrt{10}[/tex]
