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

[tex]\text {Distance } = \sqrt{ (3-(-1))^{2} + (8 - 9)^{2} } [/tex]

[tex]\text {Distance } = \sqrt{(4)^{2} + (-1)^{2} } [/tex]

[tex]\text {Distance } = \sqrt{16+ 1 } [/tex]

[tex]\text {Distance } = \sqrt{17 } [/tex]

[tex]\text {Distance } = 4.12 \ units [/tex]
