Question

Find the distance between the points (-1,-1) (1,3)

Answer 1

Answer:

√20

Step-by-step explanation:

We can find Distance between two points by following formula:

d=$\sqrt({x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

Given points are (-1,1) and( 1,3).

let $x_{1} =-1$  and $y_{1} =-1$

    $x_{2} =1$   and $y_{2} =3$

Putting above values in formula to find distance,we get

d=$\sqrt{(1-(-1))^{2}+(3-(-1))^{2}  }$

d=$\sqrt{(1+1)^{2}+(3+1)^{2}  }$

d=$\sqrt{(2)^{2}+(4)^{2} }$

d=$\sqrt{4+16}$

d=√20 is the distance between given two points.
