I'm not sure how to find AB

#

The only thing I got so far is that AC = 2i + 4j and BC = i + j

#

The solution to find AB is 3i + 3j

how did you get BC = i+j?

#

Honestly not really sure how to even get BC

#

Just guessed it bc in the question it says AC and AB is parallel to I + j

#

So just assumed that was BC

#

since BC is parallel to i + j, then BC = k(i + j) for some real k value

#

then try to formulate an equation to solve for k

#

note that k cant be = 0
