Question

What is the length of AB?
A(2,-6). BIZ, 1)

Answer 1

The length of AB is
`√(74)\ units`

Explanation:

we know that

The formula to calculate the distance between two points is equal to

`d=\sqrt{(y2-y1)^(2)+(x2-x1)^(2)}`

`A(2,-6)\\B(7,1)`

substitute

`d=\sqrt{(1+6)^(2)+(7-2)^(2)}`

`d=\sqrt{(7)^(2)+(5)^(2)}`

`d=√(49+25)`

`AB=√(74)\ units`
