Answer:
√20
Step-by-step explanation:
We can find Distance between two points by following formula:
d=[tex]\sqrt({x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
Given points are (-1,1) and( 1,3).
let [tex]x_{1} =-1[/tex] and [tex]y_{1} =-1[/tex]
[tex]x_{2} =1[/tex] and [tex]y_{2} =3[/tex]
Putting above values in formula to find distance,we get
d=[tex]\sqrt{(1-(-1))^{2}+(3-(-1))^{2} }[/tex]
d=[tex]\sqrt{(1+1)^{2}+(3+1)^{2} }[/tex]
d=[tex]\sqrt{(2)^{2}+(4)^{2} }[/tex]
d=[tex]\sqrt{4+16}[/tex]
d=√20 is the distance between given two points.
