Hi. I need help finding a vector for an equation for a line. In the question i'm given 2 points which both have the same distance to the Line.

Points (2,2) and (0,-2)

I managed to find a point on the line p1,0) by making a vector out of the 2 given points and then dividing it by half, and so on. But i have no idea how to get the vector. Anybody who can help? Thanks a lot. Been stuck here for like the past hour. Thanks again....
