- Distance Formula: [tex]\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Step-by-step explanation:
Step 1: Define
Point C(4, -5)
Point D(-3, -5)
Step 2: Find distance d
Simply plug in the 2 coordinates into the distance formula to find distance d
- Substitute [DF]: [tex]\displaystyle d = \sqrt{(-3-4)^2+(-5+5)^2}[/tex]
- Subtract/Add: [tex]\displaystyle d = \sqrt{(-7)^2+(0)^2}[/tex]
- Exponents: [tex]\displaystyle d = \sqrt{49+0}[/tex]
- Add: [tex]\displaystyle d = \sqrt{49}[/tex]
- Evaluate: [tex]\displaystyle d = 7[/tex]
