- Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Step-by-step explanation:
Step 1: Define
Point A (1, 2)
Point B (5, 5)
Step 2: Find distance d
Simply plug in the 2 coordinates into the distance formula to find distance d
- Substitute [DF]: [tex]d = \sqrt{(5-1)^2+(5-2)^2}[/tex]
- Subtract: [tex]d = \sqrt{(4)^2+(3)^2}[/tex]
- Exponents: [tex]d = \sqrt{16+9}[/tex]
- Add: [tex]d = \sqrt{25}[/tex]
- Evaluate: [tex]d = 5[/tex]
