Question

What is the distance between `(0, -5)` and `(18, -10)`?

Answer 1

`18.68` units (rounded to 2 decimal places)

Explanation:

Distance = `sqrt((x_2-x_1)^2+(y_2-y_1)^2)`

ie:
`(x_1,y_1) = (0,-5)` and `(x_2,y_2) = (18,-10)`

Distance:
= `sqrt((0-18)^2+(-5+10)^2)`
= `sqrt(324+25)`
= `sqrt349`
= `18.68` units (rounded to 2 decimal places)
