Question

Trigonometry

Length of line segment
Find the length of the line segment whose endpoints are: (8, -6) and (15, -6)

Answer 1

7 units

Explanation:

These points lie on the same horizontal line.

No vertical distance

Only horizontal distance of:

15-8 = 7 units

Answer 2

The answer to your question is d = 7 u

Explanation:

Data

P₁ = (8, -6)

P₂ = (15, -6)

Formula

distance between two points =
`\sqrt{(x2 - x1)^(2)+ (y2 - y1)^(2)}`

x₁ = 8 y₁ = -6

x₂ = 15 y₂ = -6

-Substitution

d =
`\sqrt{(15 - 8)^(2) + (-6 + 6)^(2)}`

-Simplification

d =
`\sqrt{7^(2) + 0^(2)}`

d =
`√(49)`

-Result

d = 7 units

- Conclusion

The distance between these points is 7 units
