Question

Find the distance between (1, 3) and (-2, -6) and put it in simplest radical form

Answer 1

• 
  `\tt 9.48`

Explanation:

(1,3) and (-2,-6)

`\tt Distance= √((-6-3)^2+(-2-1)^2)`

`\tt =√(9^2+3^2)`

`\tt =√(81+9) =√(90)`

`\tt Distance=√(90) =9.48`

Answer 2

`D=√(90)\ or\ D=9.49`

Explanation:

`D=√((x_2-x_1)^2+(y_2-y_1)^2)\\\\D=√((-2-1)^2+(-6-3)^2)\\\\D=√((-2-1)^2+(-6-3)^2) \\\\D=√((-3)^2+(-9)^2) \\\\D=√(9+81) \\\\D=√(90)\\\\D=9.49`

Hope this helps!
