Question

Find the distance between (-4,-3) and (-8,2)

Answer 1

The distance (r) between any two points (a,b) and (c,d) is :—

`r = \sqrt{{(a - c)}^(2) + {(b - d)}^(2) }`

Putting the values,

`\sqrt{ {( - 4 + 8)}^(2) + {( - 3 - 2) }^(2) }`

`r = √(16 + 25)`

`r = √(41)`

The distance between the points is √41
