Hi, I'm not sure what to do for euclidean distance. Any help is appreciated

Find the Euclidean distance between the points (1,2) and (3,3) in R2. (You

may leave your answer in terms of a square root.

Find the set of convex combinations of the points (1,2) and (3,3).

Graph and describe the convex combinations. (You don't need to hand in

the graph, but the description should be as complete as possible.

Find the convex combination when = 1/2.
