6) Imagine that the size of your friend’s illusion was 30 pixels. How would you explain to your friend what that means? (Explain this conceptually, do not just indicate which numbers are used in the calculation)

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
