Hey everyone, i just had a question that for some reason i can't figure out
The question is:
Give a vector parametric equation for the line through the point (-5,-2) that is perpendicular to the line <-2,-4-4t>.
I'm really confused because i tried to found the vector v = <0,-4> and then did the dot product as (x,y) . (0,-4) = 0. i get x = 0 and y = 0
can someone help me
