equation could be used to show the proper social distance needed?
-6-5 -3-2
12 3456

Explanation:

1) the required equation in common form is:

(x-x₀)²+(y-y₀)²=r², where (x₀;y₀) - coordinates, where Michael is standing; r - the social distance;

According to the common form and given coordinates (x₀=-5; y₀=2; r=6) it is possible to make up the required equation:

(x+5)²+(y-2)²=6².

2) if the distance between two friends is:


d=√((-5-1)^2+(2-1)^2)=√(37), \ then

this distance is longer than social (6 ft). For more info see the attachment.
