Question

Find the length of UV. v(2,-1) u(1,-9)

Answer 1

Answer: $\sqrt{65}$

Step-by-step explanation:

Concept:

Here, we need to know the concept of the distance formula.

The distance formula is the formula, which is used to find the distance between any two points.

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

Find the length of UV, where:

• U (1, -9)
• V (2, -1)

$Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$Distance = \sqrt{(1-2)^2+(-9+1)^2}$

$Distance = \sqrt{(-1)^2+(-8)^2}$

$Distance = \sqrt{1+64}$

$Distance = \sqrt{65}$

Hope this helps!! :)
