- Distance Formula: [tex]\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Step-by-step explanation:
Step 1: Define
Identify points
(-5, 7)
(4, 2)
Step 2: Find distance d
Simply plug in the 2 coordinates into the distance formula to find distance d.
- Substitute in points [Distance Formula]: [tex]\displaystyle d = \sqrt{(4 + 5)^2 + (2 - 7)^2}[/tex]
- [√Radical] (Parenthesis) Simplify: [tex]\displaystyle d = \sqrt{9^2 + (-5)^2}[/tex]
- [√Radical] Evaluate exponents: [tex]\displaystyle d = \sqrt{81 + 25}[/tex]
- [√Radical] Simplify: [tex]\displaystyle d = \sqrt{106}[/tex]
- [Distance] Approximate: [tex]\displaystyle d \approx 10.3[/tex]
