Question

The distance between the points in the xy-plane having (x,y) coordinates (2,1) and (6,2) is

Answer 1

Use the distance formula:\[d = \sqrt{(x _{2} - x _{1})^{2} + (y _{2} - y _{1})^{2}}\]

Answer 2

\[(x _{1}, y _{1}) = (2, 1)\]and\[(x _{2}, y _{2}) = (6, 2)\]so just substitute and simplify.

Answer 3

All good now, @jahvoan ?
