Question

Find the distance between the points (3, 8) and (-1, 9).

Answer 1

---------------------------------------------------
Formula
---------------------------------------------------

`\text {Distance } = \sqrt{ (X_1-X2)^(2) + (Y_1-Y_2)^(2) }`

Find the distance
---------------------------------------------------
Given the point (3, 8) and (-1, 9)


`\text {Distance } = \sqrt{ (3-(-1))^(2) + (8 - 9)^(2) }`


`\text {Distance } = \sqrt{(4)^(2) + (-1)^(2) }`


`\text {Distance } = √(16+ 1 )`


`\text {Distance } = √(17 )`


`\text {Distance } = 4.12 \ units`
