if (2,1) is a direction vector, better written <2,1> to show that it is a vector. it means in simple x-y space that, if you go +2 in the x direction, then you go +1 in the y-direction.

so, if you were to take a walk **along the line -x+2y-10=0**, and you moved +2 in the x direction, how far would you have moved in the y direction?

Ok so it went 2 units right and 1 unit down?
